Hi Aaron.

Yup. I have the exact same issue - except that it isn't a problem for me
since none of my domains need more than 512 MB :-). You need to compile
your domU kernel with 4GB RAM support. "cd xen-2.0/linux-2.6.11-xenU;
make menuconfig" -> Processor type and features -> High Memory Support
(off by default in domU kernels).
