I wonder if such an effort is worthwhile. If all pointers are suddenly twice the size then the footprint of a program roughly doubles. Hence to run a program that that needs more than 4GB of RAM on a 32 bit architecture you would need more than 8GB of RAM on a 64 bit machine (and e.g. Apples G5 machines only support 8GB of on-board memory). It would be interesting if Haskell programs could run in the lower 4 GB while running in 64 bit mode. Then you could have large data structures (or memory mapped files) in C land.
