Heh. How come they never hold those up here? (Well, actually, they
probably do and I just don't know enough about finding them....)

In my experience, the way GENERIC has it works just fine.

Well, scsibus* isn't the critical part; the critical part is more like
esp* at sbus? slot ? offset ? flags 0x0000 # SBus (older proms)
esp* at dma? flags 0x0000 # SBus
(esp has the scsibus property). Of course, it depends on just what the
card shows itself as; it might not be an esp. ("cd /sbus" then "ls" at
the ok prompt should produce something useful.)
Well, actually, the scsibus* part *is* critical, but it's basically
critical to having SCSI at all, which you must if the onboard SCSI
works: it's not a part you want to meddle with.

In my source tree I see
le* at sbus? slot ? offset ? # SBus
ledma* at sbus? slot ? offset ? # SBus
le* at ledma? # SBus
lebuffer* at sbus? slot ? offset ? # SBus
le* at lebuffer? # SBus
and looking at SPARC GENERIC,v 1.145 2003/02/27, I see something very
similar.
There are various other "at sbus" pieces which may be relevant (as
well, or instead), depending on exactly what's on the card - output
from those PROM commands would be very useful.

Does it have sbus slots? Electrically, I'd expect it to work in any
(non-slave-only) sbus slot - though I don't know sbus well enough to be
sure. Ancient ROM versions, such as your 670 may have, might not be
capable of setting it up right, though.
