Are you aware that upstream Linux 2.6.37 doesn't have the
xen (dom0) drm/ttm/kms fixes yet? They were just posted
to dri-devel and to lkml just a couples of days ago for review..
Konrad has a git tree with the patches applied, iirc ..
Also Jeremy's xen/stable-2.6.32.x git tree has (most) of the patches applied.
Also you might want to discuss these issues on xen-devel..
and report success/failures :)
