@Herve - Various DSDT modifications, revo script SSDT ( i7-2720qm ), dw1510 rebranded wifi card, etc. I'll write up a guide at some point in the next few days with full details. Sleep started working properly after I enabled optimus in BIOS and imported the PEG0.VID._OFF method from SSDT-4. It needs to be called from _WAK and PCI0._INI.
Also, I made a slight mistake in my last post, I'm actually running 10.9 GM, not DP8.
