If you want 802.11g support and can live with the limitations of active scanning, then Broadcom-based cards are the obvious choice (recognized as Airport Extreme cards).
If you want 802.11g with support for passive scanning, then Atheros-based cards are the only option, and they have the attendant problems that have already been discussed.
There are no other 802.11g options that I know of, at least not for MacOS X. It's either Broadcom, or Atheros. That's it.
