Working for me :-) but one annoying issue that I had before that I don't think is related.
I followed the steps and boots fine, even Sound and Mic input working without problem which is good. My problem is when I reboot, more often than not the trackpad and keyboard are inactive and I need to plug in an external keyboard and mouse to continue... clearly not practical. I have to force shutdown and start over and hope it works - sometimes but usually have to try 2 or 3 times.
When I had this issue before I reinstalled the O/S Combo update (it was 10.6.5 at the time), reran NBI, repaired disk permissions etc but none of this worked. In the end I discovered I had USB Legacy Mode Enabled and when I Disabled it everything was ok.
This time around at 10.6.8, I checked and USB Legacy Mode was still Disabled. I changed it to Enabled, no difference, back to Disabled... sometimes works. I also tried reinstalling 10.6.8 combo, rerunning NBI and repairing disk permissions but no luck.
Not really sure what else I can do and not seen many other people having this issue either. But when I do get the keyboard and trackpad back, everything is fine.
