You need to enable PAE in both Xen and Linux - they need to be a
matching setup otherwise it won't work [this is because Xen handles the
page-tables for Linux and it obviously needs to handle the same LEVEL of
page tables as Linux thinks it should be!]. 

So you need to set the 64G configuration option in .config for Linux,
and the PAE option in the Xen config file (Config.mk: XEN_TARGET_X86_PAE
= y). 

This will obviously need a recompile of both Xen and the Linux kernel...
