Don't ask how to hack password. (BIOS Passwords)

I have this old Asus F3sv laptop.

It features Intel 965 mobile chipset and came with Intel Core2Duo T7250 CPU.
I acquired Intel T8300 (penryn core - 45nm) and tried to upgrade this laptop.
I have latest BIOS, but Asus never made one with penryn support for this laptop.

However BIOS does not register new CPU, it reads it as Intel T8300 (that is ok) but it is locked on 1.2Ghz (half speed)
and current speed is registered as 100Mhz.

Anyway, it does not work as it should.
Also, I could not load acpi-cpufreq module for dynamic freq change.

I tried to update microcode from OS, following instructions from Intel website.
And it does not fix the problem.

I'm new in this stuff, how do you usually solve this problem?
Can this manufacturer limitation be fixed?
By modding/updating BIOS?
