We've been playing with it. It works fine but the sound support is non
standard, and assumes  some off-chip CODEC. it can 'trap' accesses to the
standard sound ports and emulate them using the SMI emulation system, but
that requires BIOS support.

video support is also dependent on the bios setting it up correctly.
(we use it in a server and thus don't care about either).

(oh yeah we have our own bios that ignores them too)
