I'm trying to get dual monitors to work on my Nvidia 7200GS in 10.6.4. I've tried NVEnabler and NVInject and neither work (assuming I'm applying them to work). I know people have these cards working, so what's the secret?

Also, my wifi card, a TL-WN851N Atheros based card, isn't working either. What should I do to make this work?

Thanks!
