I've seen a patch to accomplish this... somewhen, somewhere...
Look for "fastmem" or "slowmem" as keywords, but the patch did
exactly that (limit existing memory, creating a blockdevice on the
remaining MBs).

Hmm, are swapdevices being cached...? This would be a more generic
approach to the problem.
