Well, I recently had a Dual Xeon Server with 4GB of RAM. Installed Debian Sarge on it and had only 3,2GB RAM. I had to recompile the kernel with 64GB highmem support (PAE was enabled automatically when doing this). Then the kernel detected arround 4,8GB RAM, 800MB are reserved for PCI devices and voila, I have 4GB of RAM useable. (NOT with XEN, "just" an application server). Don't know if this is of any use for you, just a hint from me. Greetings, Markus
