Toshiba Satellite L650-1NT - bios modification for i7-820QM

It supports only Arrandale. Too bad.
But strange, because the PCH BD82HM55 supports 4 core processors. They are on its list.

HM55 supports Clarksfield, but this motherboard doesn't.

What are the key differences between Arrandale and Clarksfield? Is the lack of Clarksfield support due to a weak CPU power section? Since it's not the bios that's to blame or PCH?
