I haven't seen anything recent on if it works to run OES Linux on a
em64t system.

I see in
that it is listed as a recommended system for installing to. So I would
just ignore the warning about installing a 32bit OS onto a 64bit system
and continue on my merry way?
Has anyone run into any problems with it? Server will have less than
4GB ram.
