...and the XP64 support is apparently not great for some^W a bunch of
things.  x86_64 Linux is much better in this regard, but there are still
a few things that are harder than they should be, like getting Java

With PAE, you can have 64G total, but each process will be able to use a
max of about 3.5G.  PAE is also slower than going with a flat address
space.  Note that YMMV, and HTH,
