Thx Meklort for the feedbacks
Can you precise the way sound and trackpad work ? Out of the box or with a dedicated kext ?
I used NetbookInstaller (modified for 64bit support) to installer. The touchpad kext is the same one used for the Dell Mini's, it's just been recompiled as a 64bit kext. The touchpad is made by Synaptics, has the 7.2 firmware on it, and has 5 extended queries included that are probably for the multi touch features (these are not documented by Synaptics as far as I can tell).
I haven't tried anything special as far as audio goes. In other words, I was lazy and used VoodooHDA. Right now, it sounds horrible / like it's clipping (which can be fixed with a better clipping algorithm inside of the kext).
The DSDT must be patched before the machine will boot. To do this you have to fix the cpu aliases. You also have to patch the dsdt before sleep will work.
I'm also using a modified bootloader to get the USB bios / os handoff working.
As far as out of the box, Since I used NetbookInstaller (an as of yet unreleased version, I'll post one sometime), everything works without user tweaking.
