patches to update x11/nvidia-driver

[Ben Kaduk]

Hi all,

As many of you know, nvidia recently released (in april) new FreeBSD
drivers for their graphics cards.  I have installed this driver, and
it seems to work well on my GeForce Ti 4200 Go here.
I seem to recall that the port has been unusable on -current for a
while due to some api/abi changes, but the new version from nVidia
works fine.

I made some patches, though I am a novice to the ports collection and
they may need correction:

Makefile:
85c85
< NVVERSION=    8178
---
> NVVERSION=    8756

distinfo:
7,9c7,9
< MD5 (NVIDIA-FreeBSD-x86-1.0-8178.tar.gz) = ef6d63b01ff062b9f5c2dd458e7e89b1
< SHA256 (NVIDIA-FreeBSD-x86-1.0-8178.tar.gz) =
90d3fd6acf916471a6d41737e83f5ed5489effd920cb695bc44bec791262a280
< SIZE (NVIDIA-FreeBSD-x86-1.0-8178.tar.gz) = 9067056

> SHA256 (NVIDIA-FreeBSD-x86-1.0-8756.tar.gz) = 3c5e095c62cb5e57dc932a626d75e64cdd4c3c62ab9b1bab1bc0478f987b64b1
> SIZE (NVIDIA-FreeBSD-x86-1.0-8756.tar.gz) = 9427746


My laptop is not usually heavily loaded, so I was able to do a ` find
/ -newer Makefile ` without too much clutter; I didn't see any new
files in this revision, but I may have missed something.

Does this look correct?
Should I file a PR?

Thanks,
