I just tried 2.6.33 so far, without success.

Yes, that's Jan Beulich said on this list. However, I've buid a
2.6.32.11 kernel, with all xen patches available from SLE11-SP1 (as well
as a few others needed for applying xen patches properly), and used the
corresponding defconfig file. But I can't find any reference to those
drivers, at least with the names given in README file of xen tarball
(xen-platform-pci.ko, xen-vbd.ko, xen-vnif.ko and xen-balloon.ko).
That's probably just because of a name change.

Anyway (unless I'm wrong), the actual usefulness of pv-on-hvm is on
standard linux kernels, not on dom0 itself, and the issue seems to be on
xen Makefile side.
