Nice one ! I didn't think anybody shipped a DD1.0 chip ! :-)

Looks like some typo/thinko in the cputable and you are one of the very
rare victims of it. I'll fix that up. Regarding the IDE problem, can you
shoot a note to Tejun who wrote that patch (and CC me) ? I do recommend
switching to libata but we should still fix the problem with legacy IDE.
