Why don't you use the MMC/SD layer already merged into the kernel
instead of rewriting your own.  Grab a copy of Andrew Morton's
kernel, and look at the code in drivers/mmc and include/linux/mmc.

There are three host drivers there already.  I'm sure you can work
out how to interface the existing framework to your device.

And suddenly you can take advantage of the already existing mmc
block device support, which does support partitions, and does
manage to get hot swapping block devices more or less correct.
(and if it doesn't, it'll be one less driver to fix later.)
