david.hicks commands shouldn't be necessary. I found a problem. It is of
maemo-optify which is configured to auto. In cups-common /usr/lib/cups
is not optified. Therefor the previously made symlinks are hidden. I try to
fix this.

Edit: I have uploaded new, non-optified packages. They should work now,
but they take about 10MB of rootfs, which is too much for a promotion I
think. Remember, the device has to be rebooted after installation.
Please try it!
