It already is in the quirks list.
The problem is that LUN 0 does not show up on this machine, so the quirks table doesn't work. Looking at /proc/scsi/scsi shows the device but only sorta:
> Host: scsi1 Channel: 00 Id: 00 Lun: 00 > Vendor: Model: Rev: > Type: Processor ANSI SCSI revision: ffffffff
whereas the LUN that is mapped shows up like this:
> Host: scsi1 Channel: 00 Id: 00 Lun: 01 > Vendor: APPLE Model: Xserve RAID Rev: 1.20 > Type: Direct-Access ANSI SCSI revision: 02
So since the information doesn't show up, the quirks table magic doesn't work since it doesn't know that it needs to do a sparse lun scan.
