This patch against 2.6.15-rc5 might help fixing boot on some recent
powerbooks like some 12" aluminium. However, I need urgently some
testers with other models of powerbooks and mac mini to tell me if it
causes any regression (that is before tomorrow) so it _might_ have a
chance to make it in 2.6.15.
