if you know FreeBSD, NetBSD should not be a problem.

unfortunately i have same chipset. very bad choice. forget of working 
builtin ethernet for now.

works

1) almost fine on FreeBSD-current, ethernet "supported" but quickly locks 
up and renders unusable
2) NetBSD-current works fine except ethernet, there is available patch 
that behaves exactly as FreeBSD.

3) don't run NetBSD-2.0.2 - lots is unsupported system not much useful

it's Nvidia, company that's famous of not giving any information on their 
hardware, just binary drivers (with lots of bugs).
