R.e. backports.org Lenny backported Xen kernel

[Simon Iremonger <wiltslug@iremonger.me.uk>]

I have discovered, very helpfully, that Backports.org has:-
   linux-image-2.6-xen-686    2.6.32+27~bpo50+1
   linux-image-2.6-xen-amd64  2.6.32+27~bpo50+1
(and of course the actual 2.6.32 non-meta-packages)

At least the 64bit version works fine, but only with a newer Xen
   hypervisor than that included in lenny...  It seems necessary
   to build this manually.  Apparently something about the way the
   newer kernel images are compressed cannot be uncompressed by
   xen 3.2 or something...

I am finding however that the associated modules packages:-
   linux-modules-2.6-xen-686
   linux-modules-2.6-xen-amd64
Are missing!

These are very useful as a means to install just the modules on
   a paravirtualized debian-lenny guest Xen domain without installing
   the whole linux-image and boot/initrd related bits/pieces...


Would it be sensible/possible to build these too?  Are they not included
   for a reason?

With thanks,
