Umm, not for MP capability ... with the K7's, the only configuration
parameters you could change through the pins were the multiplier and the L2
cache size (the latter only if you bridged the L9 bridges). See my post
http://groups-beta.google.com/group/alt.comp.hardware.overclocking.amd/msg/2a7ab2e1e112f795
for what I mean by configuration parameters of the CPU. This is because the
pins were nothing more than connections into the bridge circuitry, so if you
drove the pins hard enough (such as doing a direct connection to GND or
VCore) you could override the settings from the more weakly driven bridge
logic.
In the case of the K8, all the configuration parameters are locked. You
cannot change any of them though bridges, since there are no bridges to
change. Also, noone has found any pins that change any of the configuration
parameters, and it's unlikely that any exist (similar to the P4).
