Well, christoph has been forwarding most stuff upstream, since he is
also a kernel developer, i tend to let him do that.

Well, the kernel svn is at :
http://svn.debian.org/viewcvs/kernel/trunk/kernel/
And the patches, both arch-indep ones and powerpc, can be found in :
http://svn.debian.org/viewcvs/kernel/trunk/kernel/source/kernel-source-2.6.7-2.6.7/debian/patches/
and in :
http://svn.debian.org/viewcvs/kernel/trunk/kernel/powerpc/kernel-patch-powerpc-2.6.7-2.6.7/patches/
As you see, most of the patches are in the generic kernel tree now, and
many of those will go away once 2.6.8 is released.
All subversion commits are logged, at the debian-kernel list, but will
get a separate list later on, i think.

Bah, optimized ? What is the difference between stuff you don't compile
in and stuff that is modular but you don't load ?

Well, you should not, it should just work. This is not yet really the
case, but we are working on it.

Ok. Well, i understand, i do kernel development also.

Well, since the debian kernels are 2.6.7-powerpc, or something such, you
just use make-kpkg --append-to-version, and you create a kernel which
can pe parallel instaleld. yaboot should be able to cope with that, or
is somewhat buggy and needs to be fixed.

Huh ? Whatever for.
