This appears to just be some diagnostic code in the MI SCSI layer which 
doesn't expect a polled SCSI driver. You could try removing the code in 
scsipi_base.c and see if it will survive anyway. Compiling without 
DIAGNOSTIC will also remove the check.

Looks like the only real solution here are some interrupt driven SCSI drivers 
which will be impossible without actually having a card to develop against.
