The device is pretty standard.  One thing I forgot to mention in
the original report is that it used to work just fine with NetBSD
on the old build.

``scsictl sd0 start'' makes a little bit of progress, and claims
to be "fabricating a geometry".  ``gpt show -a sd0'' shows two
partitions (one for NetBSD backups, and one for Windoze backups)

	# gpt show sd0
	       start        size  index  contents
	           0           1         PMBR
	           1           1         Pri GPT header
	           2          32         Pri GPT table
	          34        2014         Unused
	        2048  4294967296      1  GPT part - NetBSD FFSv1/FFSv2
	  4294969344  3518951424      2  GPT part - Windows basic data
	  7813920768       49119         Unused
	  7813969887          32         Sec GPT table
	  7813969919           1         Sec GPT header

But it does not seem to progress to the discover-wedges process,
and no wedges seem to exist:

	# dkctl sd0 listwedges
	/dev/rsd0: no wedges configured
