How I fixed my problem after the 10.6.2 update..this is odd, but it worked for me..
First I made a copy of my screwd up SL install to a USB. Then:
1. Went to:
http://osx86sv.wordpress.com/2009/10...de-d630c-d630/
and downloaded Bootloader2. Installed the included Charmeleon 1 Installer to the USB drive, Copied included Boot to USB Drive /Volumes Folder.
2. Re-installed original Audio kexts from original D630 Package in this post (the original one, before the installer) Followed Included Directions on adding the VoodoHDA Helper and preferences.
The USB copy now has bluetooth working, audio, and USB again!!! I'm going to either do the same to my main drive or just clone it over.
Update: As mentioned in step 1.. The boot file included with that fixed almost all my issues.. It runs even better than before.. USB and Bluetooth work everytime now.. whereas before they would stop working every once in a while.
If you restart and have issues with your graphics resolution.. I just reinstalled the D630 installer package (uncheck option for reinstalling chameleon and then I used HelperKext to add SleepEnabler.kext and Natit.kext back in (to overwrite the existing bad ones). Also I dont need the Ethernet so I deleted that.
