heh.  looks like I wasn't paying attention.  A long time ago, I believe the 
xensource product (3.1?) was i386-PAE only-  and 32-on-64 is 32-PAE
on 64, so you won't be able to run non-pae 32-bit guests in paravirt
mode.

But xenexpress limits you to 4Gb of physical ram total
see http://www.xensource.com/Documents/XenServer41ProductOverview.pdf 
so if you have 4Gb in the DomU, you can't use another 4Gb in the Dom0
