Linus wants this, and he stated that again on the kernel summit.  But to do
this porperly (= not the EVMS way) it needs preparation.  Al currently does
lots of work in that area to make the block drivers largely independent of
the major number.  Once the drivers don't need the major number anymore
internally the only that needs sorting out is userlevel backwards-compatinlity.

I'm pretty sure the preparation will be finished for 2.6, also I can't comment
whether the unified disk major will be done. (Al?)
