If stock fglrx, radeon, radeonhd doesn't work, use xserver 1.5.3 and radeonhd 1.2.4 from (use apt, READ NOTES FOR HARDY)

It works with kernel 2.4.24, newer drm needs to be installed from http://xorg.freedesktop.org/wiki/radeonhd:DRI

Works fine on 2.6.29 with "eata" driver, but does not support shared IRQ. Sharing irq will cause driver to crash. See motherboard manual to avoid sharing irq.
