ISTR I managed it simply by adding a "SA_SHIRQ" flag at convenient point in
the SCSI driver and making the use of SA_INTERRUPT agree between it and the
3c59x driver. I forget which I changed.

Not particularly good for performance perhaps, but it worked. I was happily
writing CDs on the thing while using it as a router. Admittedly it was only
routing on Nortel's Powerline mains power network stuff, so the traffic through
the ethernet wasn't exactly killing it, but it was quite happy.
