It sounds like it should all just work. Especially if HPUX works.
But HPUX sometimes cripples the bus speed or *wideth* based
on what PDC tells it. Perhaps you need to do the same. I really
don't expect any issues with bus speed on differential SCSIs.
Possibly a wide vs narrow bus issue (Chip thinks it's wide and the cabling
is narrow). We see that on C3k still and I started (but didn't finish)
the code to query PDC about Host SCSI ID, bus speed, and width.

Yeah - if HPUX boots/talks to the devices, they are basically ok.
It's a matter of getting the linux driver the right parameters then.
