I believe it should compile with 2.6.27 aswell.. or if it doesn't,
please let us know.

See here for PV-on-HVM drivers building instructions for SLES11 2.6.27:
http://wp.colliertech.org/cj/?p=653

If the unmodified_drivers from Xen 4.0 doesn't build for 2.6.27,
then we should definitely add the (possible) patches from Novell.

Does anyone know if the 2.6.3x Novell xenified kernels have PV-on-HVM drivers?

There's ongoing work to get the PV-on-HVM drivers accepted to upstream 
kernel.org
Linux kernel.
