Exactly the same here. Same graphic card and same problem.
I tried to solve the problem with some combinations of kernel and drivers. And the results:
kernel 2.6.31-15 + default driver set = freeze
kernel 2.6.31-15 + ubuntu-x-swat set = freeze
kernel 2.6.31-15 + xorg-edgers set = freeze
kernel 2.6.32-rc8 + default driver set = freeze
kernel 2.6.32-rc8 + ubuntu-x-swat driver set = freeze
kernel 2.6.32-rc8 + xorg-edgers driver set = freeze
These are the intel driver versions contained in the explanation above:
default driver
2.9.0
xorg-edgers
2.9.0~git20091007.03e8e64f probably to 2.9.0+git20091130.2.6729b508
I read more carefully launchpad bug reports and noticed this report:
-----------------------------------------------------------------------------
As a workaround, I've discovered that switching to EXA acceleration seems to work. To do that, open the file /etc/X11/xorg.conf and make sure you have a section that looks like:
Section "Device"
Identifier "Configured Video Device"
Option "AccelMethod" "exa"
EndSection
Then restart X and you should be able to enable desktop effects without a freeze.
Unfortunately, UXA acceleration continues not to work. If there's any information I can provide to figure this out, please let me know.

Since I am not hit by this bug I might have been somehow misguided with the launchpad reports. The reports state that this is freeze is happening when desktop effects (Compiz) are activated. Isn't this more related to libdrm-intel or libdrm2?
