Sorry I forgot to mention it - but hciconfig shows a fully 'up and 
running' interface. I use the bt950_cs driver.
I further checked and most hcitool commands work except the link quality.
I Have tried removing the bluetooth.conf from my pcmcia/ directory and 
use hciattach with /dev/ttyS03, but no success here as well (could not 
find correct parameters). Why is it the preferred way?
