Ok, so my first reply was before I made my own DSDT. I just made one and it solved my issue that was on this thread

Sooooooo....
1) Get DSDTSE from this site
http://www.osx86.es
2) When you first run DSDTSE there will be a button that says "Extract DSDT". Click on that and it generates the uncompiled DSDT of your current system configuration. The uncompiled version of a DSDT is know as a .dsl file.
3) Backup your current configuration by saving the untouched .dsl file. You do this under File > Save .dsl
4) Then go to Tools > Compile DSDT. You will probably get some errors that won't let you compile. Don't panic, this is normal. If you are familiar with programming in C++/C#, you'll know that errors won't let you compile, while warnings will allow you to. So warnings aren't a big deal but you want to get rid of all errors.
5) In the list of errors in the compiler window, each error will show an explanation under it as to why it's an error. Under the list called "DSDT Fixes" those explanations will be there. If you click on the explanation corresponding to your errors, it brings up a little tutorial of why it's a problem and example code to copy into your DSDT to fix it.
6) Simply replace/delete/add the code it says to for each error until you can compile with no errors.
7) Once it compiles with no errors, go to Tools > Install DSDT, for "Install DSDT on:" choose your HD that OS X is installed on, check the box next to "/Extra", and then click "Install".
NOTE: Only follow step 7 if you AREN'T going to use MultiBeast to install your DSDT
8) Reboot.
If you are going to use MultiBeast to install the DSDT, which most people are going to you, just go to Backup > Backup .aml to save your compiled DSDT and when you run MultiBeast copy the .aml file to your desktop because that's where MultiBeast looks for it.
In the DSDTSE program there is a list called "DSDT Hacks" which is a list of a lot of the major issues that need to be fixed, where applicable. By applicable I mean if you have a ATI card, you don't need to do a NVIDIA fix, and so on. The video I linked above also has a few fixes listed in it with step by step instructions. I would watch that video before I tried using DSDTSE because it gives you a general idea for how it works.
Hope this helps.
