Patch looks basically good to me (I basically have the same thing sitting
around here, as I was cleaning up drivers/block/genhd.c) If you want to I 
can send you what I have, so you can base the further changes (e.g. PCI) 
on it.

I'd suggest to go ahead and make it return sensible values, i.e. -EBUSY if
it can't get the major, -ENODEV if there's no hardware, -ENOMEM if the
allocations fail.

This should be static now. Also, you need to remove the explicit call to 
cpqarray_init() from drivers/block/genhd.c, otherwise it'll get called 
twice. (That part's already in my patch).
