D830 Intel 1920x1200. Same issue, fixed with AppleACPIPlatform.kext from 10.6.7. I'm also using native speedstep, by setting smbios.plist to Macbook5,1. It seems to me that before 10.7.4 it would drop CPU voltage to 1.09 and now doesn't drop past 1.15.

I had trouble getting native CPU scaling to work on 3,1. I've switched to your DSDT. I haven't noticed any difference functionally, but it sure is nice to have one that doesn't generate compile errors. Any changes I should be aware of, having switched? Native support for anything I was using kexts for previously? As for graphics, I'm not seeing any real performance drop since SL. Mission Control is choppy, and so is resizing windows once they're bigger than 1024x800 or so. Maybe I'm accustomed to slow OSX performance, since it's been pushing 1920x1080 this whole time. Still not one graphics glitch. 100% correctly displays everything. I don't have any kexts that should be making me run glitch free. Just the usual voodoo items, and the ones from vmware fusion.

I haven't noticed any graphics glitches, but definately some lag when there's too much open. I'd accepted poor graphics support as my lot in life with the x3100. I've just spent about 10 minutes opening, closing and resizing windows trying to generate some graphics glitches. So far, everything has drawn to screen flawlessly. Maybe a bit laggy though... What system definition are you running in? I'm on MacBook5,1. I'll give your dsdt a shot too. I'm always searching for one that's better than what I've got. Thank's for your response, I'll let you know how my search for graphics glitches goes.

Fully working, here's what I've got for those that need it. Backup your IO80211Family.kext and IONetworkingFamily.kext files from working SL install. Install with kextutil on Lion to restore wireless. Remove AppleACPIBattery if you have it. It will KP on Lion. Install the latest VoodooBattery after install. Make sure boot.plist is set for i386 kernel. Video drivers won't work on x86_64. If you have bluetooth, you may get messages about no keyboard connected after install. Go to system preferences/bluetooth/advanced and tell it not to pop up the wizard if no keyboard/mouse are detected. USB kb/mouse only while in installer. Built in will work again on first boot. May need to remove AppleHDA.kext to boot properly after install. Not sure, but I deleted it. I'm using voodoohda. I've attached my working DSDT, install it first and you'll have video support during Lion installer. It isn't based on the current one available on this site, and I don't remember where I got it. It's been modified to support the IOPci introduced in 10.6.8/Lion and is set for DVI dual link. dsdt.aml.zip I've attached a modified version that :SHOULD: work for those of you with the 1280x800 screens, but I have no way to test it. dsdt.aml.1280x800.zip Hope this helps somebody out, I sure spent enough time working out all my issues. Also a thanks to the countless posts by countless people on countless sites I searched through to get all this going on day 1.
