didn't try speedstep yet... what will it do? improve performance? (and more importantly, what kext to remove from terminal in case it cause boot problem?!?!

Anyway, my main issue is network: my Realtek network adapter is not recognized at all. The wireless IS recognized (rt2860), but it receives "bad CRC" on all packets.
maybe I'll order the BC eventually (its usu 3-4 weeks delivery time from HK...) - BTW, there are eBay sellers which sell it for $15..
