I'm working my way through that now. It seems pretty likely that there's
a mis-association between the OBP's idea of where hardware is and where
it really is. I did note that "boot cdrom" doesn't result in even a
flicker of the CDROM drive light -- and that light is known-good -- so
this suggests that OBP isn't even looking at the drive.

Yes it is -- already snarfed and copied to three different devices. ;-)
Further update: one of the two systems I'm working on happens to have
a bootable disk in it, as I found out while fooling around with "boot disk0"
and similar. (Not my install, this is a leftover from the previous owner.)
I now have that system up and running OpenBSD 3.9 in single-user mode --
which doesn't help that much toward getting OpenBSD 5.0 installed, but it
has let me do one thing: test the CDROM. I popped in a Solaris 2.7 CD
(first thing I found) and yep, I can mount and read it. So this would
seem to indicate that I've got good cabling, good power, and a working
CDROM drive. What I don't know (to Patrick's point in his followup) is
whether that drive will function okay as a read-only device while it's
a secondary master *but* won't boot the system while that's so.
Further OBP self-education and experimentation commencing momentarily.
