I know it's usually considered poor form to followup-to one's own post, but I
continued tinkering and made some small progress.  It seems that if I swap
SCSI cables around so that the EXB is on the 2940 and the system disk on the
1522A (the disk is somewhat flaky and won't share a bus with another device),
I get a stable working configuration.  The downside is that the 1522A is 2-3
times slower than the 2940, so my nice fast system is now a touch sluggish.

For grins, I tried '/usr/src/sys/i386/isa/aic6360.c' from 2.2-GAMMA, but no
luck.
