I don't know how much of a 686 the Geode ("586+cmov") we use is, in
the sense that I hope people (Chris, Deepak) have looked at this and
ensured there are no other dragons lurking.

To note: it _is_ reported as a 586, so at least ancillary work in
yum/anaconda/rpm will be needed so that installing F12 on these
