OK. That's an important step.

Quite probably. Just unpack the .tar.bz2 package somewhere else and you
will have the tree that was used to compile your kernel.
Actually, a hint here: it is *not* necessary to compile your kernel as
root. In fact, it is a good idea to use the root account as little as
possible. The compilation of a kernel (or of a module) is not one that
would require being the root user.

Usually, /lib/modules/<version>/build is just a link to any place where
the kernel is put. You can see where it is pointing to (or if it is not
present at all) with something like:
ls -l /lib/modules/2.6.26-2-powerpc/build
When you unpack the kernel sources (and you can put it anywhere you
like), just make sure the link cited above points to where you unpacked
your kernel.

The compilation script/makefile that came with your module is looking
for the kernel headers where /lib/modules/<version>/build is telling.
Anyway, are you really sure that you wouldn't like to use a newer
kernel? The 2.6.26.x kernels are way, way too old.
Hope this helps,
