Elliot Nunn a8c1a4de1c Definitive ATABoot patch ...

Key realisations:

1. The driver entry point only needs to be called once per disk,
   not once per bootable partition. Bootability is decided elsewhere.

2. As a result, my shim code does not need to access the disk at all.

3. None of the ROM-based ATADisk drivers support "slave" drives.

4. Apple drivers (contrary to the Monster Disk Driver Technote) only care
   about D5 (the drive ID and some flags) on entry.
