-For native Linux support, a development snapshot of the "madwifi" driver, which uses a non-free binary-only HAL, can be used. It does not support the draft 11n protocol, but will work in "legacy" 11g mode.

+Madwifi is a native linux driver that used to use a binary-only HAL and so must be compiled separately from the kernel. The HAL has recently been opened up, however with the development of ath9k mentioned above, the future of this project in particular with regard to this chipset is uncertain. It does not support the draft 11n protocol, but will work in "legacy" 11g mode.
