Which mATX 478 mobo's allow Vcore adjustment?

Hi,
I plan to put p4 mobile on mATX mobo. Since p4 mobiles (on desktop mobos) are detected as 1.575V cpu's, so I need to _decrease_ the Vcore.
Please help me and name any !!microATX!! p4 478 mobo that allows Vcore adjustments, or put links or information that can help me decrease voltage on mATX board in other way.
thanks!
