Without loading the DRI module, it works. I attach the Xorg and kernel
logs, this time with 2.6.17-mm1 kernel. The good thing, it does respond
to SysRQ, somehow. I can reset the keyboard mode and reboot cleanly.

The only thing I note by looking at the X log is that previosly it was
running over lots of /dev/dri/card* files and stoped at:

drmOpenDevice: node name is /dev/dri/card13
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: Open failed
drmOpenDevice: node name is /dev/dri/card14
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: Open failed
(EE) RADEON(0): [dri] RADEONDRIGetVersion failed to open the DRM
[dri] Disabling DRI.

Yeah. And this time, we get:

drmOpenByBusid: Searching for BusID pci:0000:02:00.0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 7, (OK)
drmOpenByBusid: drmOpenMinor returns 7
drmOpenByBusid: drmGetBusid reports pci:0000:02:00.0
(II) RADEON(0): [dri] Found DRI library version 1.2.0 and kernel module version 
1.24.0

And the screen is black and strace log shows this looping over
unsuccessfull syscalls.
