Dell Latitude D610, Pentium M @ 1.86Ghz, 2GB RAM
running uptodate FC4. 100% reproducable since
2.6.15-git6, no problem up to -git5. Log in to VT1, run
startx, fire up a gnome-terminal, exit it, Desktop->Logout...
at this point the mouse arrow stills and the box locks up,
keyboard dead, no response to pings.
Card is, according to lspci -v,
00:02.0 VGA compatible controller: Intel Corporation Mobile
915GM/GMS/910GML Express Graphics Controller (rev 03) (prog-if 00
[VGA])

Doesn't happen on -git6 on my older laptop (Latitude C640,
Pentium IV @ 1.8Ghz, 1GB RAM, Radeon Mobility 7500), so
it definitely is hardware-related.
Diff'ing the dmesg boot log and the Xorg log from the latest
working version to the latest available version, the relevant
lines would seem to be these:
