Toshiba M45-S331 CPU Upgrade Possible?

I have an old Toshiba Satellite M45-S331 with a Pentium M 730 CPU (1.6Ghz). I think the Pentium M series of processors went up to something like 2.2Ghz. I was going to give it to my daughter (10 yr) to play with, but I wondered if I could upgrade the CPU. The 730 has a 533 FSB which I think is the fastest FSB these processors came with and it is a socket 479 which I also think was the only socket used for these processors. Looking at Wiki, the core voltage is the same for the 533 FSB units (1.26–1.356 V) up until model 760 (2.0Ghz). After that, the core voltages go to 1.26–1.404 V. Of course the multiplier is different as well. Would it be possible to upgrade to a 760 or higher?
