Are any other Thinkpads currently using the same WiFi and Audio chipset as the Helix, and if so, has anyone gotten those models to work on OSX 10.8.x with WiFi and audio?

I have ML running on the Helix quite nicely, but I have no battery/power management, no screen brightness control, no WiFi, and no audio. Webcam (user facing) works fine, and everything else runs quite nicely. Pen works OK, but cursor drifts as you move away from the center.

Thoughs, help, advice?
