If I'm not mistaken, the new XEN kernels have PAE built-in already.

How do you know your memory isn't reporting correctly? How much RAM
does dmesg, top & xm top show respectively?

I know there was a problem with grub, which needed to be recompiled if
you added more RAM, or changed the kernel before it would see more
than 3GB RAM. Maybe this is what you need todo?

I don't know if this bug is still a problem,

Take a look at this:

It might help?
