What kind of problems are people having?  I've had really good success
with quite a few similar boards:
both using Digital audio with passthrough or analog.  The only quark
I've ran into is the component output on the M2NPV-VM that unless the
correct TVStandard is set it produces a blue hue over the entire
screen.  Otherwise, it is a very nice board for FE/BE combined systems
(as well as a straight FE system).  For a backend the PCI's are quite
limited and it seems like overkill for video, so I wouldn't necessary
recommend as a standalone BE.

I don't really know what to include in a wiki page because I didn't
really have to do a whole lot of 'non-standard' stuff to get it
working as desired in Gentoo.  Fedora took a little bit of sweet
talking, but overall it wasn't that much different.

So, if anyone can post up some of the problems they had (whether they
have them fixed or not, if it's fixed, the fix would be good too ;) )
I'll be happy to build a wiki entry with some steps I take and include
some config files in it.
