Yet another data point.  I've seen this with RedHat 9 and i810 and
2.5.67+. I've haven't had time to test without AGP yet

I could avoid the freeze by starting X with "startx". Then, when going
back to runlevel 3, the freeze did _not_ occur. 

I saw the freeze when selecting "Log Out" from either KDE or Gnome, but
only if I started X with /sbin/init 5.

Occasionally and with 2.5.67-mm1 only, instead of a freeze, I saw a
spontaneous reboot.

I'm many miles from that test box now but if I get the chance I'll test
without AGP.
