I have similiar problem on 32bit CentOS5 and 6gb of RAM: with
kernel-PAE all memory is indeed recognized, but with kernel-xen not
(which has PAE support also).

But AFAIK 64bit OS should "just" work and see all your memory. Which
debian version / xen packages do you have installed?

I will try next installing the 64bit version of CentOS5 and see if
that makes a difference in my own case.

Cheers,
Peter
