Close, but not quite.

You can take a vanilla 2.6.10 or the Debian patched 2.6.10. I would
recommend the Debian patched one. You uncompress the kernel-source
somewhere, copy in your .config, that is fine.

The command you wish to run is:

  make-kpkg --added-patches=xen --arch=xen --subarch=xen0 
--revision=xenserver.0.1 debian

This patches the kernel and creates the ./debian directory in your
source. After that you can run:

  make ARCH=xen menuconfig

And tune it to your liking. And after that, you compile the kernel:

  make-kpkg --added-patches=xen --arch=xen --subarch=xen0 
--revision=xenserver.0.1 kernel-image

And you are done. Not all of the flags need to be present in all
phases, but it doesn't hurt either. Do also note that make-kpkg has
some problems with --initrd combined with --arch=xen, so don't do
that.
