Many nForce2-based boards are using a Attansic ATXP1 chip. With this 
chip it's possible to dynamically change the processor voltage (Epox 
8RDA serie: 1.075V - 2.2V).

Other boards:

Abit NF7
Aopen AK79D-400VN
Chaintech CT-7NJ(S,L1)
DFI Infinity NFII Ultra
DFI Lanparty NFII Ultra
Leadtek K7NCR-18D
Shuttle AN35N Ultra
Soltek 75FRN(2)-L

But the nForce2-chipset doesn't support AMD mobile CPUs, so it's maybe 
not the best for this.
