seemingly there is something wrong with the permissions for udev to set the ACLs on these devices

this does not seem to happen on mako (image 196 though, i.e. the android 4.2 kernel)

also please enable /proc/config.gz in all Ubuntu Touch kernels ... it is hard to find out about such options since we do not install the package and thus have no /boot/config-* file installed (the kernel binary gets pulled into the boot.img creation during teh android package build only)

After some IRC discussions it was decided to pull the /boot/config* file into /system somewhere instead.
