Laptop Upgrade - Fastest Processor

[stubie_doo]

I currently have Toshiba Satellite Pro L40 laptop which has an Intel Celeron M 440 processor (Socket M).

I am trying to work out the fastest processor that I can upgrade too. The motherboard chipset is I943/940GML and after a bit of research i have discovered that I need to stick to processors which have a 533MHz FSB.

I am now having trouble trying to determine whether the chipset will support core 2 duo or core duo cpu's.

Has anyone upgraded a laptop with this chipset or have an idea what the fastest processor is that it will support?

I looked at the T2700 but that has a FSB of 667MHz

The T2450 seems to be the best choice but I'm struggling to determine whether the new bios update will support it as Toshiba don't have any release notes.
