You can clone the linux-2.6 Mercurial repository from kernel.org and
serve it locally, its not hard to revert to version x and then diff from
Y to present to see what changed. Or if your comfy with git, you could
get to it a little quicker. 

You'd then need to adjust patches/* in your xen tree accordingly where
you can so they 'just work', then manually apply the hunks that won't.
That is a painful, frustrating process because you have to project how
Xen would have patched differently based on what they did in your
current version.

Unless its just a few minor things that changed, your end result can
only be buggy, its better to wait for xen-devel to jump. If you have to
edit the patches beyond a few lines, count on the end result being
buggy.

If its something like.. a function somewhere was changed to take less
arguments, you'd probably be ok.

They are about to get rid of the sparse tree anyway. When that happens
you can just build your dom-u kernels like you would any other. I
figured something big was about to change when 3.1 didn't hop kernels.

Best,
