Do we understand either of these (i.e. Broadcom or Atheros) helpers well enough to utilize them? If so, it sounds like a nice feature to support. Hardware/firmware may be able to do nifty things to save power. If we don't really know how those helpers work, it may be better just to remove the unused infrastructure. Is my opinion useful? :-) John -- John W.
