If you're really good, you can get some of those BIOS editing tools, and
find where this multiplier value is, and change it. Similar stuff has
been done to the P2B BIOS, in order to have it recognize the tualatin
celeron microcode:

I am still thinking about trying something like this with an old P2B board
that I have, which throttles the processor cycles (speed) down due to an
apparent faulty harware monitor chip (even tried flashing to no-hardware
monitor BIOS, it still thinks the CPU is overheating)...
