Yes, that's what I mean. I just want to check the repository every night
and if a change is found to recompile xen-hypervisor, xen-tools,
xen-kernel, xen-modules pack it into deb-packages and put it on my
private debian ftp-server for all my xen-machines. BUT where's the
repository?! Is it http://xenbits.xensource.com/xen-3.0.3-testing.hg ?

Ahh...

Right, but if Xen wants to get into the Linux kernel Xen must be
available in every kernelversion after entering the kernel (e.g
2.6.16.ab, 2.6.17.cd and so on should contains Xen). I know, Xen is
still not available in the official kernel but why can't I download just
a patch for my desired kernel? Xen-hypervisor and Xen-tools should be
independent by kernelversion XOR available for every kernelversion.

Yeah, nice. A developer answered...

That's good to hear but one question. Where is the repository of the stable 
Xen-versions? E.g. 3.0.2? I just can find
http://xenbits.xensource.com/xen-3.0.3-testing.hg .
