I'm glad it does.
And just for completion, the current generation of AMD processors
derive the CPU clock from the memory controller clock instead of the
FSB. Moreover, the memory controller clock may also be changed on the
fly and is thus subject to power management policies too, effectively
making its TSC not invariant if the memory controller power is
managed. However, I don't know of any OS that does this yet.
