Userspace (so also /lib/firmware) was same (mostly the basic LXDE rootfs
with some additions).
The LXDE rootfs and also qtmoko ships with
the debian libertas-firmware package.
I tried also the firmware from the firmware-libertas package in debian
unstable/backports after that. It does not change things much.
