Actually, mixed mode simply means a combination of interpreted and
compiled code, which is the norm for both HotSpot and JIT.

I believe the 64-bit version reports PA2.0W (W=wide) in the version
string.  I'm not sure about it's availability; someone indicated at
least 1.4 might be required.

If you look under /opt/java/bin (or wherever you have java installed)
and don't see a PA_RISC2.0W directory, then I suspect you can't run in
64-bit mode.  If you do have it, I don't know off the top of my head how
to invoke it, but java -X would probably give you the proper option.
