I've been loading the Linux kernel from CompactFlash (CF) (raw image) in
/dev/hdc1, and then mount the root disk in /dev/hda1, and this is pretty
fast.  I shortened the delays in the IDE routine since the CF doesn't need
spin up time.  We really need an "intelligent" routine to find when an IDE
device is ready rather than a pure time delay.
