As Byron said, it really should be sufficient to just upgrade the kernel
(I presume that you already have a CPU that is 64-bit capable: not very
many boards with old CPU's can even fit 64GB of ram).
In fact, I wish more people did that, just so that we'd get better
coverage of the 32-bit compat code. We occasionally find issues there,
although I think it's getting rarer.
