I take back my word. Got full analog 5.1 to work on my onboard alc888!

1. Tweak AppleHDA.kext to detect 3 Line Outputs: Green, Black, Orange.
2. Run Audio Midi Setup
3. Add new Aggregate Device
4. Click on the 3 check boxes corresponding to the 3 Line outs
5. Click on Configure Speakers
6. Select all 3 streams
7. Select Multichannel 5.1
8. Make sure all channels are properly mapped
9. Select Aggregate Device as output under System Preferences>Sound
10. Done

Here's my modified AppleHDA.kext as reference
