I haven't tried suspend/resume, but starting with 3.7, the nouveau
driver stopped working on my ancient GeForce card. This email about
"not supporting msi" is the first clue I've found *anywhere* on the
Internet about what the issue might be. The symptom is

1. Boot the machine
2. Log in to any desktop but KDE
3. Start Firefox. The machine immediately locks up with random streaks
on the screen and needs to be power-cycled.
4. KDE doesn't even get to the desktop - the lockup / streaks happen
as it's painting the screen.

I had to switch to 'nv' in xorg.conf to get the machine to work with
3.7 or 3.8 kernels.
