Oh, well, did the ppc64 2.6.11 kernels i provide work there ?

Can i have a bit more context ? The full log would be welcome. BenH can you
comment on this ?

Yeah, yeah, it was just a quick build, the rest of the stuff is coming, and
the flavour name will be -pseries.

Hehe, yes, i believe so, the source is in the debian kernel svn repo right
now, Well, actually to create those, i just took the pruned patched debian
source package out of the above repo, and ran make-kpkg on it, with the ubuntu
glibc and gcc-4.0 installed, nothing much more. You need kernel-package 9.0002
though, or a patched version.

Sure, but you would want pseries and pseries-power4, the legacy-iseries
variant is not for you though, and as i know nobody who has one and can do the
testing, i am only somewhat keen on producing an image nobody will use.
