This is a Number 9 Revolution 4 video card.  Problem occurred with non-updated
brand new FC3 install and also after I patched everything (including kernel and
xorg-x11): kernel-2.6.10-1.770_FC3 xorg-x11-6.8.2-1.FC3.13

lspci -v output

It seems to only happen after the second logout from X.   I already tried
commenting out "Load dri" in xorg.xonf and that did not help.  KDE/Gnome are not
installed - this happens with twm and XFCE.

The system is totally dead after the second logout.  Won't respond to pings,
keyboard, or mouse.  Only the hardware reset button.

I also posted a report with Redhat at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=154114

They had some suggestions (e.g. disabling hw accel) which I will try today and
then follow up here.  I've also posted xorg.conf and a log file there.  I can
repost them here if needed but it looks like I have to paste them in as text
rather than attachments?
