That sounds reasonable.

I think I have an add-in card that also shows up as esiop.  That could
help me tell whether it's the hardware or something weird in the
driver.

Actually, I got the machine from a friend-of-a-friend who was a pretty
hardcore SCSI geek in a former life (he now repairs organs, the musical
kind).  He would probably be the right person to ask about this; it's
not totally implausible he might even have source to the firmware (I
doubt he could release it to me if so, but he could look at it).
