AMD (as I'm sure some of you know) supplies docs for the k6 and k8 on cpu init, but doesn't for the k7, making things very difficult.
#21656, but only available under NDA I think?
The northbridge is the amd 751, which amd has also all but destroyed the docs on
#21910, on AMD's public website just fine, perhaps not too easy to find, but it's there (look in the "historical" section).
