6-STABLE and CURRENT have the same hal so I don't see how it works 
differently.  Verify the hal versions.

Regardless this problem is caused by a batch of cards D-Link created 
with bogus regulatory domain codes programmed into the EEPROM (they 
programmed 18 when they probably wanted 16 = FCC).  If you search a bit 
you can find postings that describe how to "fix this".
