Not at present. The scsi subsystem will only probe for a host adaptor
if there are none present. Furthermore, it is sd.o that is associated
with block-major-8, so there's not really any place to hook on.
Perhaps one of the scsi folk can comment on the advisability of probing
for additional host adaptors if a device beyond the number currently
detected is opened. And if it is not evil, whereabouts would be a good
place to hook on.
