Different chipsets
There are at least two chipsets which are both referred to by Lenovo as "ThinkPad 11a/b/g/n". To find out which one you have you may have to update your pci id list. You can then use this list to identify the hardware on your pci bus.
#update-pciids #lspci 00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub (rev 03) 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) 00:1c.0 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 1 (rev 02) 00:1c.1 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 2 (rev 02) 00:1c.2 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 3 (rev 02) 00:1c.3 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 4 (rev 02) 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 02) 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 02) 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 02) 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 02) 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev e2) 00:1f.0 ISA bridge: Intel Corporation 82801GBM (ICH7-M) LPC Interface Bridge (rev 02) 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 02) 00:1f.2 SATA controller: Intel Corporation 82801GBM/GHM (ICH7 Family) SATA AHCI Controller (rev 02) 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 02) 02:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet Controller 03:00.0 Network controller: Atheros Communications, Inc. AR5418 802.11a/b/g/n Wireless PCI Express Adapter (rev 01) 15:00.0 CardBus bridge: Texas Instruments PCI1510 PC card Cardbus Controller
In this case, the wireless card is in the second to last line of the output from lspci.

Linux WiFi driver
There's now (04.04.07) added experimental support for the AR5008 chipset to a new branch in MadWifi. I have compiled this driver successfully, but it's still at an experimental stage, so no promises are given. Howto
There is an old ticket for this card at madwifi, #1001.
There is an new ticket for this card at madwifi-branch, #1243.
To install this driver, just checkout the branch madwifi-hal-0.9.30.13.
mkdir /tmp/madwifi cd /tmp/madwifi svn checkout http://svn.madwifi.org/branches/madwifi-hal-0.9.30.13/ cd madwifi-hal-0.9.30.13/ make make install *choose [r] reboot
News fron the madwifi-branch:
* milestone changed from version 0.9.x - progressive release candidate phase to version 0.9.4. FYI: the madwifi-hal-0.9.30.13 branch has been merged to trunk (and the branch has been removed). If you don't want to wait until the next release (v0.9.4), you could go with a snapshot or checkout from trunk - just make sure that your code is >= r2360.
Until the madwifi driver stabilizes you might want to get the Windows driver from Lenovo's support site and use a recent version of ndiswrapper (>= 1.29). I've compiled a Howto for this card.
AR5418 is still to new?
If anyone is able to get the AR5418 to work with madwifi, please add your procedure for getting it to work - in the meantime, ndiswrapper works with the windows driver.
Update 10.06.2007 from Stevie:
I have the AR5418 chipset and with the snapshot release r2431 this chipset works (with wpa-psk). Just try it...
Hardware switch
Some ThinkPads have a hardware switch that must be in the on position for the radio to work, regardless of driver state:
In addition to hard-switching the wireless card, the switch also generates an [Acpid|acpi event] on transition from hi->lo and vice versa. It is however the same event regardless of the direction.
