Does using DSDT eliminate need for kext files?

Hi - I am having some moderate difficulty with getting my graphics card working using DSDT. I have an 8600GT 256MB. I used Tony's tutorial. Didn't work. I did find two things odd that I had not expected. First odd... my card is 256MB. The flag should be 0x10. IORegistryExplorer says 0x40, which translates to 1GB. Second, my NVCAP values were identical to the ones in the example. I didn't expect that... Given the example used a 9400GT, I expected a different result.

So, assuming I have set things up right, does it eliminate the need for additional files? If we shouldn't use NVEnabler or the GraphicsEnabled switch in Boot.list when we use DSDT as the example says, how do I get this card to work?

Don't hack your DSDT for graphics, prefer a gfx-string or Graphics Enabler from chameleon

Are you speaking about your preference, or what works the best?

I was under the impression that the order of reliability/desirability was something like:

1. No mods necessary
2. Mods in DSDT
3. Kext and enablers.

Did I get that wrong? Do I need the kext files even if I am successful with adding whatever device to my DSDT?

Usually DSDT shouldn't be used to inject pdevice properties, and chameleon is the recomended way.

There's differents types of kexts: apple's kext that are used on real macs, and hacked kext: full drivers (like voodooHDA) or injector that help apple's kext working.

You have to use apple's kexts to get acceleration, but enablers as kext aren't that good and you may prefer chameleon automatic injection.
