Not a good idea! Windows uses the top of the memory for file
caching. And according to ct this gives a big performance penalty on
machines with >64MB memory.

Probably it would be a good idea to use memory above 64MB on
Triton FX/VX/TX boards (and some others) as _fast_ swap space.
(Eg allocate the memory as ram disk and than use it as swap device)
Where in memory are ramdisks located?

However, I think this is still broken (as is the idea to use more
than 64MB in these machines).
