Therefore, can anyone confirm for me if I upgrade to 2.6.39 or 3.0.0, will I still be able to use my Linux vservers (I really do NOT want to have to rebuild them all within another virtualisation environment)? Or has Xen become the defacto (and possibly only) virtualisation system that Debian's pre-packaged kernels will support?
There are also Linux containers (lxc), but as I remember, there are limits to what these will virtualize, i.e., they aren't a complete virtualization solution at the moment. I can't remember the details, and, in any case, those details change as the kernel develops. I know this doesn't answer your question, but you may be able to run the guest systems in containers if the features supported by kernels you're prepared to use are adequate.
