The transition from old-style IDE to libata-based drivers means the
new kernel may need different drivers from the running system. We
already handle the change of controller driver correctly since we find
driver modules via module aliases. However for the disk driver
(sd_mod or ide-disk) we look at which types of devices exist in the
running system, so we may not select the one we need.
Since all the controller driver modules depend on the core modules
under drivers/ide or drivers/scsi, we can work out which disk
driver(s) may be needed by checking whether those module
subdirectories have been created under the target directory.

I've given this a very little testing and it seems to do the right
thing. This obviously needs careful review!
