I haven't seen it mentioned.

I guess you want a Tyan board then. But I think they're mostly server
class boards so a bit expensive.

K8 is really well supported by LB.

Onboard graphics is what gets you into trouble. You'll almost always
need to solder today. Not many boards ship with socketed flash,
especially not in the desktop segment.

Sure, but they're never socketed from factory. You would have to hack
some hardware together.

The current support for NVIDIA was written by Yinghai while at AMD
where he had access to all the neccessary data sheets. I'm not sure
if he's still got access to good docs from NV?
