The issues with this system using either Mountain Lion (10.8.x), Lion (10.7.x), or Snow Leopard (10.6.x) have been resolved with the help from people in this thread and through many, many hours/days of trial and error on my part. To anyone with this system setup, I have provided zip archive(s) with all the files that I have either previously used or currently use on my Mac partition(s). They have been tested working on either 10.8-10.8.2, 10.7.3-4 or 10.6.8 and are all ready to use, just unzip them, apply them where they should be, repair permissions and rebuild mkext as needed and reboot.
The only issue I that couldn't be fixed is the random restart BIOS hang where the Dell splash boot-up screen will "hang" or "freeze" once the loading bar reaches full. CTRL+ALT_DEL doesn't fix this, the only way to resolve it is to press the power button to shut the tower off and then on again. This only seems to happen when rebooting from a Mac install. I can confirm that the BIOS hang doesn't happen after a reboot from a Tiger install. I might look further into this later.
Lastly, My system is running BIOS rev A05 during all tests. So I can't confirm the dsdt provided working on anything but that BIOS rev. It may also not function properly if used on a different size chassis of the 760, such as the full size model or ultra slim form factor model.
Thanks for everyone's help!

Soooooo basically, I suck at this. I'm horribly unconfident in every aspect of DSDT creation/modification. I'm ashamed to admit but in all the years i've been tweaking and playing around with OSX86 I have NEVER been able to really figure out how to deal with using/editing DSDT files. My experience lies only with "dirty" hacks, through modification of current system files, or adding in new ones.
I have looked up and tried out more tuts than I care to count, each had their own specific way of going about it and NONE of them were very helpful. They all seemed to only cater to one specific motherboard type while leaving everyone else with a different board in the complete dark. Being lost to begin with, the last thing I planned to do was make guesses and risk completely f***ing up my hardware in the process.
So yeah, I need help. I would probably benefit most from learning from the work of others on MY own DSDT, not someone else's. So, I will provide
I only want a few patches applied because most everything on my system is working great! At least, according to my testing anyway. I was planning on applying the following patches but need help:
-RTC reset fix for CMOS.
-GeForce device/NVCAP injection (see below for code, originally referenced here)
-SpeedStep enabling (never attempted, I think it might be dangerous)
-Audio fix for ADI 198x (if exists, although i'm content with using current VoodooHDA solution)
-Sleep/Hibernate fix (should one exist, this one is VERY low priority)
-Network/Ethernet fix (also low priority, i'm currently using AppleIntelE1000e as a fix)
EVGA GeForce 6200 512MB PCI NVCAP:
0400000000000300040000000000000700000000**This code was extracted using Everest Win7x64, then using NVCAP Maker v1.4.
That's really it. Most everything else important seems to function as expected. If someone with long time experience in creating/editting DSDT files reads this, I hope you'll considering helping me. I'm eager to learn this but not so eager to destroy hardware through constant trial & error, which is all I have going for me right now. So if anyone can and is willing to help, please try and do so. I will really appreciate it! If more info is needed i'll do my best to get it to you ASAP. Thanks for the read.
UPDATE: So, I decided to try to test out my edited DSDT linked above to see if it made any difference. Low and behold it appears I actually might have fixed a couple things. After testing it out and rebooting the first thing i noticed was that my RTC fix worked! My BIOS no longer resets after a reboot! I previously needed ElliottForceLegacyRTC to fix that. Then, I tried out my tiny graphic fix (to try to make sure my PCI was correctly read as 0. That seems to have worked too. Before the edits, I needed to use NVEnabler to get my 6200 to give me the black screen before the login screen, now it does it by simply adding the GraphicsEnabler flag. Lastly, I did a rough fix to my PIC & TMR and planned to edit my HPET which never was done because I didn't know what I was doing and didn't wanna risk frying my CPU. Still, I edited both PIC & TMR and tried to see if I could get my system booted without the need for the NullCPUPowerManagement kext and it actually worked too! Although, to be fair, I am pretty sure I didn't need to edit anything to get my CPU to work without NullCPUPM before. I just had it in my E/E folder to be safe.
Either way, i'm completely baffled by the fact that my half-assed attempt at a DSDT edit ended in slight success, especially since it gave me a s***-ton of errors while building. I still have a few fixes I REALLY need help with though. I don't have an audio fix, a sleep fix, a speedstep fix, an ethernet fix, or a GeForce injection. So please, if anyone has anything that might be able to help me, i'm all ears!
UPDATE#2: Tried adding in the Nvidia NVCAP injection linked above without success. Back to square one since QE/CI + Full resolution is STILL the only important thing missing from my system. I also keep getting a crapload of errors while rebuilding my DSDT for testing, which I can only imagine might lead to unforeseen problems later on potentially.
UPDATE#3: Installed SnowLeo on a USB HDD to test with to see if the 6200 would even work on that. Long story short, no it doesn't. That means I would have to go back as far as Leo just to get this stupid card to have full QE/CI. So I decided an upgrade was in order, after much discussion with Gringo, another forum member who was very helpful in the decision process, I have purchased a 9500 GT that should arrive within a few days. Hopefully my luck with QE/CI will change once I give the new card a try. Nothing could be worse than the slow ass, outdated, PCI-based 6200 I have been testing with. Will keep the thread posted on progress.
