Currently, I am not the backport maintainer and there is a new
backport tree:
        git://linuxtv.org/media_build.git

The new build system is a improvement from the last backport tree idea.
Basically, it's a .tar file from the current -git tree which is
updated regularly.

For while, this new tree is able to compile until 2.6.31.
I just back from a long business trip, I will try to help with kernels
< 2.6.31 but
cannot provide you any date.

Cheers
Douglas
