[Request] CPU upgrade - Toshiba A500-17x PSAR3E

Dear friends,
I am hoping that someone might help me.

I would like to upgrade my CPU to a speedier one.

Bios Link:
http://support1.toshiba-tro.de/tedd-files2/0/bios-20120530194425.zip

Current CPU: Link: http://intel.ly/1Gkikpn
Intel® Core™2 Duo Processor P7450 (3M Cache, 2.13 GHz, 1066 MHz FSB)
(Socket P - PGA478)

New CPU: http://intel.ly/1CfN5e9
Intel® Core™2 Extreme Processor QX9300 (12M Cache, 2.53 GHz, 1066 MHz FSB)

New CPU variant 2:
Intel® Core™2 Duo Processor P9700 (6M Cache, 2.80 GHz, 1066 MHz FSB)

I triple checked all available information, and the Chipset Model - GM45/GM47 supports the QX9300 CPU, as well as the P9700. (Just the QX9300 has a higher TDP value and if it will work I will proceed to create a custom heat dissipation system for this laptop to support the higher TDP).

Please, if anyone can help - I would like to request a modded bios to enable support for this CPUs.

Would it be possible such a CPU change modification?
