dsdt.aml only fix some warnings and add the HDEF and DTGP code for ALC887.
you need to install the AppleHDA.kext to make ALC887 work.
using GraphicEnabler= yes in the *boot.plist to make the vedio card function
after installing ALXEthernet.kext ur Ethernet will be ok.
that all works for 10.8.2
Thx for the guys who provide us the drivers above.
