I've done that in the past, when the problems started with kernel 2.6.37.
Couldn't find anything that improved the situation.

1) Resume/suspend with any kernel older than 2.6.37 works without a hitch, no
MCE.
2) Besides resume problems, the machine is rock solid with both older and newer
kernels.
3) When nouveau is blacklisted, there is no MCE. The machine wakes but doesn't
activate the monitor correctly, I can however ssh into the machine.
4) I have no problems with resume/suspend when running Windows 7 on the machine
and no crashes either.

Semms unlikely to me that if the hardware truly is faulty the only situation it
ever shows up is when nouveau is loaded during a resume from suspend with a
kernel newer than 2.6.36.
