[Problem]
X freezes after about 1-2 minutes unless XAA used.  The system has 64MB so XAA
is not getting forced on by default.

This is a regression from Intrepid to Jaunty, verified as still affecting
Karmic, and tested against git up to commit f39cafc5 via xorg-edgers, and by
another user with the same hardware up to commit 20090805.bd03977e.

[Original Description]
Hi,

I did a clean Jaunty install. Now I have the problem that the System freeze
randomly. I cant't reproduce the freeze. It happens randomly 1-2 times a day at
browsing with firefox, searching with Gnome-Do or nautilus or at idling.

The Keyboard and mouse stop working too. REISUB doesn't work, have to push
Powerbutton to power-off system. 

Intrepid works fine, there was no problem with freezes.

Version 1:6.12.99+git20090629.f39cafc5-0ubuntu6 was tested and found to freeze
the system within 1-2 minutes.

I turned on Compiz and the System is freezing after a few minutes. Tried the
workaround setting AGPmode to 1 / 2 / 4, doesn't help.
