OpenBSD's hp700 port supports these cards, so you could probably scarf
some info from there. AFAIK, the real hold-up is finding how to access
the SGC bus on the hp400 machines, since that info would have to be
disassembled from the bootrom.
It'd be cool if you could do this!

I've had plenty of trouble with these drives and NetBSD. Not sure where
the problem is, since I've even had troubles on port-sparc which uses the
more robust machine-independent SCSI driver.

This stuff just means that it can't find a disklabel on that drive (either
because it's not on the drive or because it's not talking to the drive
properly). These errors aren't fatal in and of themselves.

There's no need to make a swap 'filesystem' under NetBSD. The 'approved'
method is to add an entry to your /etc/fstab:
/dev/sd1b none swap sw

sd6? Take a look at your dmesg output, and you'll notice that the sdX
numbers don't correspond directly to the SCSI ID. They're numbered from
lowest to highest address in sequential order (if you have ID3 and ID6,
they become sd0 and sd1).

Ouch. I added an entry to the FAQ.
Good luck,
