You may want to make the use of tagged queuing an optional thing.  If
experience with Suns and some SCSI disks is anything to go by then
some disks which claim to support tagged queuing do not function when
it is enabled - the main hard disk in the machine I am on just drops
off the bus after a while if tagged commands are sent to it.
