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.
