I may have been wrong .. someone asked John where he got the idea about
66, and I don't know where I got that idea either, but I have used that
setting since the release of 2.4.0 and it works good.

Anyone else using ATA66 or ATA100 and 2.4.x know about this?  Of course
it's not specific to the guinness .. so we probably shouldn't be
discussing it here .. my apologies.  http://vger.kernel.org for info on
the linux-kernel mailing list (I haven't subscribed yet myself).
