Ugh! Flashbacks to my Amiga 1200 days where I had a hard disk that didn't
spin up in time for the Kickstart to read it.  Later revisions of the
AmigaOS added a delay loop here.

A saner method would be to poll the IDE ports for a 'ready' signal.
But what about systems without IDE ?  We could add a timeout to the
poll loop.. Hmm, more thinking needed.

What does /proc/nvram make of LinuxBIOS ?
Or are we not setting that up yet?
