A followup:  I popped in the Advansys card thrown in with the scanner
in addition to the "real" SCSI card, and after some futzing with Linux
to get it properly recognized, scanning worked a treat.  I saw lots of
disk I/O right around the place in the process where it all got wedged
before;  the system must've been unable to write to disk while
scanning.  Disturbing if true, but the separate bus seems to be a
practical workaround.
