MSI 865PE Neo 2-P Platinum
Everything works out of the box except the lan which is easily fixed with http://sourceforge.net/projects/realtekr1000/
and sound which doesn't give 5.1 SPDIF digital out. The analog outs work fine, I haven't tested the inputs. The ins/outs might be reversed though can't remember, because I use SPDIF out.
I was able to get digital SPDIF working with 2 channel PCM (still no digital pass-thru) by editing the AppleHDA.kext and adding the device and vendor id in the ICH7 and ICH8 sections. I may have only needed to edit one section though. Then when I checked the apple midi setup and sound prefs I had SPDIF out as an option and it works for stereo output.
