I have been meaning to build test kernels for Ubuntu users for a while, but I the Ubuntu wiki documentation for building kernel packages [1] that I have used before seems to not work that well anymore. Btw, which kernel version is it best to patch? A recent drm-intel-next or 2.6.34-rc2? On -rc2 I get problems with intel-agp.c:

gomyhr@storhaugen:~/src/linux-2.6.34-rc2$ patch -p1 --dry-run <../fix-i8xx-gtt-cache-coherency-v6.patch

and I get the same with drm-intel-next. Should I just delete this file, since that is what the patch seems to do? (I tried this, and the build seemed to work, but then some of the Ubuntu-packaging failed).
