As far as I know, they are different.
Sun's version has MSI support, quiesce support,
I think better xVM support, ...
The link to the latest Sun version of 177.80
(NVDAgraphicsr package version is VERSION=177.80,
REV=2008.11.05.10.16) can be found in this thread:

Hmm, in about 30% of the fast reboots I get a warning
that the kernel is unable to allocate 64kbytes of contiguous
memory (needed for page tables?) and falls back to a
regular boot.
I think that's just fragmented memory.

I suspect you are using "force_fastreboot = 1" ?

There are still problems with MSI interrupts with the 101
version, esp. with GeForce 6150 GPUs. See the thread
I mentioned above. The REV=2008.11.05.10.16
nvidia module is supposed to fix them...
