I can also confirm this bug on Ubuntu 9.04 on a PII-450 with a Voodoo 3.
I can login to a normal X session, but scrolling an image causes a
crash, and in general X is very unstable, with GDM crashing a lot.

The workaround, as mentioned above, is to set:
Option   "NoAccel" "true"
in the "Device" section of xorg.conf

This has serious performance penalties in a 2d environment.  Searching
the net for this issue reveals the issue being discussed in 2006, around
the time Ubuntu 6.04 was the newest release.  It seems that some
resolution was found and committed upstream after that.

Note that no issues were noticed in Ubuntu 8.10 on the same machine.

I do not understand the root cause of the problem, but this seems to be
a regression. I hope someone can help shed some light.
