I tried 2.5.67-ac1 with AGP and no CONFIG_DRM, with Intel 82810E DC-133
CGC [Chipset Graphics Controller]. With that configuration, I saw the
freeze once (not easily repeatable) on _starting_ the X server (init 5)
after a successful termination of the X server with /sbin/init 3. The
freeze is 100% repeatable when selecting "Log Out" from KDE or Gnome
after X was started with /sbin/init 5. If X is started with "startx",
"Log Out" always successfully terminates the X server with no freeze.

This is with RedHat 9.
