           Summary: dom0 @32 bit can not "see" more than 16GB of ram

It seems impossible to let the 32 bit dom0 addressing more than 16GB of memory.
My environment is a system with 26GB of ram, centos 5.0 32 bit,
kernel-xen-2.6.18-53.1.14.el5.centos.plus. I've installed a upgaded xen and xen
libs downloaded from the web site: xen-libs-3.2.0-0xs.centos5 and
xen-3.2.0-0xs.centos5. 
Moreover I installed the last grub from the grub web site configured to accept
the mem parameter at boot.

I've done many posts at the xen mailing list about this problem.
