The LEDs don't work on this card. You can enable soft led operations in the ath driver if you want the LED to function:
More work would be needed to have the "LINK" light work from the ath driver, but not that much more. All the necessary functions appear to be exposed. The hard part may be finding the GPIO pin for the link LED, since none of the first 20 pins seems to do the trick. And after messing around with them for a while, both LEDs are on solid no matter what.
Still, for a card going into an appliance, this makes a great choice. Plus an easy hacking project if someone wanted the leds to always work.
