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"

The kernel module doesn't work out of the box with the 2.6.16 kernel, you get undefined symbols such as module_get_request when inserting the module. The following patch to firegl_public.c fixes it (from http://www.stanchina.net/~flavio/debian/fglrx-archive/msg01158.html ):

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)
