You would have to swap out the motherboard in order to run 64 bit systems, and that would probably cost just as mush as it would just to buy a new laptop...
I've done a little research, and it looks like you are already capable of running a 64bit OS (the core 2 duo T5850 supports EM64T or x64 architecture). The problem is that to utilize it fully (to take full advantage of what you have with it), you'll need at least 4GB of RAM. I would suggest upgrading the RAM to 4 gigs, and then installing the 64 bit OS.
