This is a very similar problem that we had when calculating prime
alternating knots[1]. Essentially what was done was to use MPI[2] 
and a fast network connection, such that you could have _other_ 
computers holding data in RAM/SWAP.

Parallelize parallelize parallelize.

It's really easy to learn MPI and it's great for those big problems
that you may not be able to do with a 64-bit box :)

a. Get a 100MBit/1GBit switch and NIC's.
b. Get some more boxes (borrow/lie/cheat/steal)
c. Tie them together.

This is what I do for a hobby :) ... and yes I'm a student aswell.
It's nice to see that people like Bell and Nortel are willing to 
donate expensive gear for projects like yours or mine[3] :)
