It depends on the target.  32-bit x86 yes, 64-bit x86, no.

Does it really consume that space, or does it merely pre-allocate that
much address space?  I think it's probably the latter.

But 640M really is a lot.  Is your -Xms setting 96M too?
When I tried running x86 Java with no options, I got a RSS of
12m, not 640M.  What are you measuing?
