[linux-pm] Memory allocations in .suspend became very unreliable

Hi,

I know that this is very controversial, because here I want to describe
a problem in a proprietary driver that happens now in 2.6.33-rc3
I am taking about nvidia driver.

Some time ago I did very long hibernate test and found no errors after
more that 200 cycles.

Now I update to 2.6.33 and notice that system will hand when nvidia
driver allocates memory is their .suspend functions. 
This could fail in 2.6.32 if I would run many memory hungry
applications, but now this happens with most of memory free.

I added some printks to function used to allocate memory in nvidia
driver and found out that contrary to my belief, they don't allocate
much memory there.

Here is the log:
