This seems to be pretty evil and creating interesting failure conditions for users who load IDE or SCSI modules. I've seen it trip up a number of people in the past. I think we should only ever use the major number that was actually allocated to us.

We certainly should be pushing everyone toward using the 'xdX' etc
devices that are allocated to us. However, the installers of certain
older distros and other user space tools won't except anything other
than hdX/sdX, so its useful from a compatibility POV even if it never
goes into mainline, which I agree it probably shouldn't.

Then perhaps we should deprecate non xd block devices starting in the near future (3.0.3?). We probably need to have it deprecated for a few releases since I think most people are not using xd at this point...
