This is somewhat expected.

You're not using the experimental free noveau kernel mode-setting
driver.  So the kernel can't restore the video card state.  You're
relying on the proprietary X driver to restore the video card state.

There are a couple of quirks like the "s3 bios" one, which may be used
to try and get the BIOS to re-initialize the video card.  (You can
find more about this in the documentation for the s2ram command on the
SuSE wiki.)  But I wouldn't bother with it; there are many different
combinations and there's no guarantee that you'll find a working one.

See above, I guess.  It's clearly not working on your machine.

It's not very clear what you mean.  But I doubt there's much you can
do about it, other than trying to installing the experimental noveau
driver.  I don't see why pm-suspend should do that, other than a
driver bug of some sort.

If you want to isolate the problem, you should try the open source
stable NV driver for X.  On some (most?) systems it is even able to
resume the video card.  Even if it can't, you're saying your problem
happens before resume, right?  So if it still happens, you would then
be able to ask for help from the open-source devs.

Or ask on the NVIDIA forums.  Last time I looked they had a couple of
active devs supporting their linux drivers there.
