I was under the impression that BIOS automagically does translation to get
around this.  It uses some geometry for disk I/O and, transparently, a fake
geometry when talking to things like DOS.  There's a "large hard drive"
HOWTO (or something like that) which gives gory details.

If your BIOS is newer than, say, mid-nineties, I don't think this is really
an issue, and hasn't been for over a decade.
