Thanks for the feedback.

It would seem then that the best solution for us is to use the debian
kernel packaging tools to create a common kernel which would then be
installed into dom0 and domU along with the matching modules.
Alternatively we could make the dom0 modules available in the guest
domains by mounting /lib/modules read only (as block devices or via
NFS).
