I haven't managed to try RHEL6 beta yet, but some comments still.. :)

You could just do:
make xen
make tools
make stubdom
make install-xen
make install-tools
make install-stubdom
And then grab xen/stable-2.6.32.x branch manually from jeremy's xen.git.

You could try my .config files that are derived from Fedora 11/12/13:
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.32.10-pvops-dom0-xen-stable-x86_64
Copy that as .config and do "make oldconfig"

Does RHEL6 still use mkinitrd? I thought they switched to dracut.

Yeah, it's better to use 2.6.32 based dom0 tree.
