The problem turns out to be (obscurely) documented in
http://www.debian.org/releases/slink/#errata. The stock rescue disks will
not work with AHA-2940s due to conflicts with the other compiled in SCSI
drivers, and a special "only-aic7xxx" rescue image is required to boot. It
would be nice if the documentation of this requirement was moved from #errata
into the "current" install document, and the aic7xxx-only rescue image copied
from its present (comparatively obscure) location of ftp://kalle.csb.ki.se/pub/
to ftp://ftp.us.debian.org/debian/dists/slink/main/disks-i386/current/ with
the rest of the rescue images. As it is, I would never have found the
documentation of the problem nor the rescue image if some kind souls
had not pointed me to them. Had the "only-aic7xxx" rescue image been present
in the canonical location, I would have deduced the proper solution immedately.
Anyway, thanks for the response, and extra thanks to Mr. Norris, Mr. Hammar,
and anyone else involved in providing the special aic7xxx rescue images.
Another Debian box is on its way to service.
