It''s really not the source tree you need to point to, but the object
tree
(which can be the same, but don''t have to, but even if they are it
implies that a certain level of building must have happened in that tree,
namely iirc up to ''make prepare''). I am actually about to send
a patch
to correct the respective instructions in unmodified_drivers/.
