How to build a Debian xen dom0 kernel with patches?

[Berni Elbourn <berni@elbournb.fsnet.co.uk>]

Hi,

Re: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=517449

Can I help move this forward? I have two systems suffering this pain...

There are some patches mentioned for 2.6.26 and also mention of 2.6.29.

I am sorry because I can not get Google to tell me how Debian Xen
kernels are patched and built :-(

How does one build something like
xen-linux-system-2.6.26-custom-xen-amd64 with those patches?

Also assuming the fixes are already included in 2.6.29....how should I
build a Debian xen-linux-system-2.6.29-custom-xen-amd64?

I am familiar with make-kpkg...

Big thanks,

Berni
