Chipset dependant?

[A van Staalduijnen <cpufreq@toptracker.com>]

At home I am running an old desktop box, running an Athlon XP on the old 
VIA KT133 (not KT133A) chipset. Since this box is mostly idle I am 
considering doing the old Athlon bridge hack, to turn the cpu into an 
Athlon XP-M, thinking I could be using cpufreq then, in order 
dynamically scale it's frequency.

I wonder though if it would suffice to turn the cpu into a 'mobile', or 
if it would require to have a different chipset on the motherboard as well.

Any chance cpufreq will work after modding the CPU on this motherboard, 
or would it be useless?


Thanks,

Arjan
