It does indeed allow the driver to enable the card. The two attached
drives do appear in /proc/scsi/scsi now, but they do not seem to be
bound to major/minor numbers. If I read the discussion correctly, I
should at least be able to write garbage to the disk and read
(possibly different) garbage back, but that is not the case.
I've included the complete dmesg output from a kernel without the
extra region requests.... I'm not sure what other information would be
useful at this juncture.
