Major:
Such a simple question. The best answer I can come up with is "maybe". NVIDIA
claim that many of the in kernel AGP drivers fail to save/restore enough state
when suspending/resuming
(http://us.download.nvidia.com/XFree86/Linux-x86/1.0-9755/README/appendix-q.html
and search for "lose their" ) and thus this is the source of the problem.
The nv driver doesn't make use of AGP so it would never be affected by
this problem (but then again NVIDIA haven't given anyone but their own
people the specs for their cards. Work to get the open source nv driver
going with 3D portions of these cards over AGP has to be achieved slowly
through reverse engineering - http://nouveau.freedesktop.org/wiki/ ).
It is unclear whether NVIDIA have sent patches to fix the issues they
claim are in kernel AGP drivers. It seems that NVIDIA prefer to carry
their own agpgart implementation and I believe there are other open
source drivers for different graphics cards that use these same in
kernel AGP drivers and do successfully suspend and resume. Given that
the source code for the NVIDIA drivers is closed, it is unclear exactly
where the problem lies and whether it is the NVIDIA binary driver/in
kernel AGP drivers that are doing something untoward/not doing enough.
Currently only NVIDIA can know for sure.
