It seems, that even the newest HAL doesn't support my DWL-G520 Card. :(

Maybe, it would be wise to modify the following entry:

****************************
      The following cards are among those supported by the ath driver:

      Card                 Chip      Bus        Standard

      [...]

      D-Link DWL-G520      AR5212    PCI        b/g
****************************

in the ath(4) man-page.
