Sun made external `shoebox' devices that had these boards in them, so
it's possible that anyone might cable one up, although it's more
likely in the sun3/sparc world.

A kernel option sounds like a good idea.  Name suggestions?  How about:

options	  SCSI_OLD_NOINQUIRY	   # support old devices without INQUIRY
