shilohh: thanks. i'll try that even though i'm not sure how (i'll look it up).
i can only invoke sleep from the finder menu and it won't wake up if i do. there are no sleep options of any kind in my control panels, which kind of surprised me because i think they were there before i did the DSDT step (on my initial install). my SSD seems a little slow too. boot up and desktop loading take longer than i expect, and it does that 'you can't use the mouse or keyboard for 20 seconds' thing when it boots up, but otherwise it seems to be great. certainly a lot easier and more useful than any other hackintosh i've built.
for the rest of you: my fans all run a little faster and louder than i'd like. BIOS shows no details of them, so i think it's something with the fan connectors not being real 4 pin connectors. buy cheap fans and you get cheap fans. since other people are saying theirs work fine, it's probably my hardware.
i can also say that multiple graphics cards are no problem, and you can mix AMD and nvidia. ethernet speeds are remarkable, and i thought my last machine was fast. this is one of the best--and easiest--hacks i've ever built. shilohh deserves an award. a major award.
