A couple of things: the Jaz doesn't mode sense, so the geometry
can't be `found' automatically.  A `fake' geometry works fine.

The DMA problem is because NetBSD doesn't support bounce-buffers.
To use an ISA DMA card, you need to limit memory to 16 MB :(
Your best bet would be to get a $70-$100 NCR/Cymbios logic-based
PCI SCSI host adapter.  (810/860 doesn't have BIOS, so you
need NCR bios on your motherboard or you can't boot; the Wide
825/875 have BIOS).
