What you say about the atheros card an i7's is interesting: I used to have trouble connecting to a network with mine.
Ah, people, it appears that even if using a other persons DSDT might work, it is not ideal as the DSDT may contain calls to RAM addresses that might exist on a board with 6GB but not with 2GB, for example. So to make things short, using someone else's DSDT is OK but you can expect errors or more frequent KP, so it's best to build your own with tutorials.
I've been working on sleep, and with the little understanding I have I think that the two basic things are C-States and S-States in the DSDT. S-States are there, and should be functional, but C-States on the other hand must me extracted in conjunction with P-States and whatnot, modified and only then inserted in the DSDT. I have made a DSDT that compiles, just for the fun of it, but when I do get my rig again (tomorrow, I hope!) I'll build one ground up and a tutorial. If I do make progress with sleep to work, I may delay it until I can do it all at once (with sleep).
