At this point I'd say stick with kernels in domU and use pygrub. Seriously.
What domU do you use? Kernel/xen version in domU does not have to be
exactly the same as dom0. For example, RHEL4 (and Centos) has
kernel-xenU while RHEL5 has kernel-xen. It was compiled against
xen-3.1.2 source, but you should be able to use them as domU kernel on
any dom0 with xen >= 3.1.2.
