Libraries are going to bite you.
This is what I would do:
Virtualize the whole box, and run it as a guest on the new hardware. You'll still get 85-90% of the performance you would have gotten with a full 64-bit stack.
Then, if you want that last 10-15%, migrate your data to 64-bit applications on the host machine, one at a time.
Enterprise's virtualization features are pretty sweet.
