Yeah, sounds like Novacom driver issue.
I just flash mine to CM7 A2.1 about 30 minutes ago, no install issues.
Ran into the known WIFI scanning/force close bug on WPA2.
No surprises, just click "forget the network" and re-connected, turned off
wifi sleep, and seems okay now. Will try to use WPA to see if it is a viable
workaround.
