Cool! FWIW, This sounds very similar to the AVID Cinema PCI card with the
exception that it probably doesn't use the DAV bus. I just gave mine away,
but there's another board that you might be able to get ahold of with a
similar setup. Of course PlanB and Sixty6 don't really work on anything
other than classic MacOS AFAIK.

On I2O RAID controllers under netbsd it seems to be able to figure out
devices by type code. Maybe Jason would know since I think he cowrote some
of the I2O subsystem.
