Proprietary ATI driver
Proprietary fglrx driver version 8.24.8 adds support for the x1400 chipset (according to ATI changelog). It works, including dualhead, 3d and video (XV) acceleration, when using the fglrx kernel module. (Without it, you get screen corruption including underlined mouse pointers.)
Sample "Device" section for xorg.conf:
Section "Device"
Identifier "ATI Graphics Adapter 0"
Driver "fglrx"
Option "ForceMonitors" "lvds,crt1"
Option "Centermode" "off"
Option "VideoOverlay" "on"
Option "OpenGLOverlay" "off"
Option "OverlayOnCRTC2" "0"
Option "PseudoColorVisuals" "off"
Option "HSync2" "31-64"
Option "VRefresh2" "56-75"
Option "UseFastTLS" "off"
Option "Mode2" "1280x1024,1024x768,800x600,640x480"
BusID "PCI:1:0:0"
EndSection
XVideo support using the VideoOverlay option may not work with recent drivers. With version 8.29.6 of the fglrx driver, you can instead use
Option "TexturedVideo" "on"
Use the xvinfo utility to verify if XVideo support is available.
Linux kernel Framebuffer driver
Works with the VESA driver at 1280x1024 (you have to append vga=794 to the kernel boot parameters). Does not work wirh vesa-tng at more than 1024x768 :(
The VESA driver can be made to show higher resolutions, if you just use lower color depth -- the best fonts sizes on 15.4 widescreen were achieved with 1400x1050 at 16 depth (highcolor).
