Starting up X locks up my machine

When I start up X on my machine the machine locks up entirely.
If this happens with gdm all you see is a gray frame where the login window should be and then things are frozen. The animated cursors before that is shown properly however.
If you start X from the console by typing "X" it freezes right-away.
This is "Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)".
Any improvements with new rawhide kernel/intel 2.5.0 driver?
The problem is still unchanged even with current rawhide.
But, I now get a differnt Xorg.0.log output. Will attach. It seems to suggest that this is not actually a problem of the intel driver, but of evdev instead. Also, the machine is not completely locked up. Logging in via ssh still works.
When I switch to the "vesa" driver the problem goes away.
I'll also attache my xorg.conf.

/me wonders if that has anything to do with the "Video Bus" devices showing up as input devices in /proc/bus/input/devices. I'll attach a dump.

CC'ing evdev guru.
nope, this isn't evdev. what happens is that the graphics driver hogs the server, so all input events that are processed during SIGIO are appended to the event queue but never removed.
After a while, the EQ starts overflowing - causing all these warnings and the backtrace (for debugging).
So these warnings mean that the evdev driver still works happily, but the graphics driver doesn't.
This appears to be a dup of a different i945 bug - there is a test package listed in that bug to try.
