A bit off topic, but I have recently gotten FFI working on 64 bit Linux:

However the changes are rather extensive and are not yet complete for other
platforms, so I would not expect this to be quickly incorporated into the VM
distributions.

There has been some progress on other plugins as well, summarized here:

  http://lists.squeakfoundation.org/pipermail/vm-dev/2007-December/001703.html

FilePlugin, SocketPlugin, BalloonEnginePlugin, BitBltSimulation, OSProcessPlugin,
XDisplayControlPlugin and AioPlugin have been 64 bit clean for a long time.

So progress is slowly being made.
