The nvidia driver knows a lot more than nv. It can tweak both X and the
kernel to do things, it is much easier for nvidia to support s2ram.

Here's what the upstream dev thinks about this:
< bgoglin> aaronp: what's the status of s2ram with nv? should work?
buggy and might be fixed? wontfix?
< aaronp> My understanding was that it works as long as the system POSTs
the GPU on resume.
< ajax> which only works if the BIOS is there to be POSTed.
< aaronp> right

You might want to try passing -p (or maybe -s) to s2ram in case it
helps. Try switching to VT console before suspend too.

But there is nothing more to expect from xserver-xorg-video-nv.
