Many thanks all,

I've decided to do the following:

Upgrade to Xen 3.2.0 using the 2.6.18 kernel (debian tree) for
my dom0 machines and build 2.6.25 kernels for my domUs. I can't
see any major howlers with this as the domUs won't rely on
anything linux/version specific in the dom0 kernel?

My major problem with 2.6.25 was that I was trying to build a
64-bit kernel which caused the config system to disable Xen.
Quite explainable if xen is not yet available for 64-bit in the
current linux tree...
