Thank you!

Right. A better way would be to compare against the K8 CPUID, and switch the 
jump direction in jmp_if_k8. That should be enough, until AMD decides to 
devise a new scheme for future CPU generations.

Attached patch does that, but is totally untested (in fact, I patched the 
patch directly)
