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.
