I'm not familiar with that card, so I don't even try to guarantee things will
work with it.

This isn't a driver problem, this is a generic SCSI issue. We don't probe all
luns by default because lots of devices are known to break when you do. In
order to get the other luns to show up you can add them one at a time. During
the install you can switch over to VT2 (which is a shell prompt) and type:
echo "scsi-add-single-device a b c d" > /proc/scsi/scsi
where a is the SCSI host number, b is the bus number (almost always 0), c is
the target ID of the device, and d is the LUN that you want added.
