It doesn't matter as far as MY box is concerned.  I use VMWare extensively
in my current $DAYJOB, and I want to be able to test/play with things related
to that as well.  The box I'm building will be using the (free) VMWare Server
as it's virtualization platform.

I'd still like to hear from a Tom Lane or someone else on the project with what
X86 or X86_64 OS's we need coverage for.
