Yes it is. The cisco programs (ACU and bcard) use an ioctl() that is
available in the airo driver too. Differences in the displayed link quality  
find an explanation in the way the raw value read from the card is normalized 
to obtain a percentage, through empiric bounds measurement.  
The raw link quality value is available from /proc/driver/aironet/eth1/Status or 
Stats IIRC (lower value is better).

best wishes,
