The real question is whether this code is limited to adding only SCSI
major numbers, or if it could be used to assign major numbers to
other subsystems (sorry I haven't looked at the code yet)?

From our discussion last week, it _should_ be able to assign major
numbers to other systems like EVMS, which you would probably want to
use on top of those 2144 SCSI disks anyways. However, since you are
billing this as the "2144 SCSI disk patch", I thought I would confirm.

Cheers, Andreas
