Oh well, it required quite some time to figure this out now.

There should be a 'dock_station' capability as far as I remembered,
however, you were right and it wasn't there :)

The referring HAL patch (attached) got reverted in upstream HAL because
the kernel wasn't ready at that time. And in the meanwhile...I completely
forgot about it :-( So also the GNOME utility relies on a capability
dock_station and thus doesn't work at all at the moment. I'll try to push
the patch again and will add it to the openSUSE distribution until a new
HAL release is made. However, this may last quite some time because HAL
development is frozen because of DeviceKit.

Regards,
 Holger
