20376 is not currently supported. Promise do have their own GPL driver
which handles this device as if it were a scsi adapter. In the same way
that Jeff Garzik has realised we need to go this path for smart SATA 
stuff so have promise.

Figuring out what to do about all this for 2.4 is on my pending pile
still - do we merge a minimal support into base 2.4.x as FreeBSD did
with their support or do we merge a scsi layer driver that can actually
make use of the command queueing (not neccessarily tagged) on the device
and/or the hardware XOR engine.
