Well, if you're going to do this, at least make it possible to tie all the sd devices to a single major (i.e. the numeric compatibility layer simply maps to the new single major scheme internally). It would also be nice for numeric compatibility to be a compile time option too...
It's also possible that SCSI may not be the only consumer of such a compatibility layer (IDE also has multiple majors), so it may be worthwhile putting it somewhere more globally useful (like fs/block_dev.c)
