This is definitely a problem known within the community (there have been
at least five reports of this in the four months I've subscribed to this
list). Sadly, the Atheros folks have remained silent on the issue,
claiming that AR5008 is actively supported (the newer AR9xxx hardware
presumably is supported, however it can't be found in hardware available
to consumers).

The situation is extremely frustrating; especially considering that the
problem is likely quite tractable to someone with hardware
documentation. Perhaps if more people complain the Atheros folks will
begin to listen.
