The D-class is very similar to Cxxx - ie it has U2 or Uturn in it.
parisc-linux currently only supports GSC devices below the first IOMMU.
Ryan Bradetich is working on "I/O tree" support to enable support
for multiple IOMMUs - then we should be able to walk additional
GSC busses and find more devices.

Probably because GSC bus with your Bluefish (FWD SCSI) isn't being walked.
That's something Ryan wants to fix once IOtree support is at least
sort-of working.

Send Ryan cash. ;^)
