Because AMD GX and LX share little with the AMD64 architecture. From
looking at the CAR code, it does a lot of its work with MTRRs. Geodes do
not have MTRRs, so it just won't work as-is. (they have similar
functionality to MTRRs, but they are not compatible)
As Hao is suspecting, AMD64 CAR won't work on Geode.
There isn't anything in LB to do CAR (but it would be possible).
