Getting 10.6.8 on AMD

[Visioneer]

I've followed a few guides. I've tried a few versions. I can get 10.6.8 to boot. I have extensive boot args I need to apply to get it to boot properly but it works. I don't have QE/CI because I have a Radeon 6950. Has anyone successfully done this?

Anyways my compy;
AMD Phenom II X6 1090t B.E. 16x@200
ASUS Radeon HD 6950 (with unlocked shaders) gfx
ASUS Crosshair V Formula mobo (990 chip)
16gb 4x4gb G.Skill Ripjaw DDR3 1600 RAM
Creative Soundblaster X-Fi Titanium
ASUS 48x DVD/CD Burner
Rosewill 74-in-1 Card Reader

Like I mentioned, I can successfully install (using ModUSB) 10.6.0 from a retail disc, OR 10.6.2 from a retail disc, OR 10.6.3 from retail disc. All of them can install and boot using

arch=i386 -v maxmem=4096 busratio=16

And then what I do next is install the 10.6.7 combo and before restarting I install the 10.6.7 Legacy Kernel, and then I restart. Once booted again with the same args, I install the 10.6.8 combo and 10.6.8 Legacy Kernel. At this point I run multi-beast to get Chimera, ElliotforcelegactRTC, EvOreboot, FakeSMC, NullCPUPowerManagement, and Kext Helper b7.

This can install fine and I can reboot into OSX again with the usual Args. Now, using chameleon wizard, I can set all my args to auto run at boot so my startup is nice. And I can even force the resolution to go to 1440x1024 (even though I selected 1920x1080). I have 2 monitors and it only detects 1 of them and mirrors the other. To get this to work, I add

graphicsenabler=yes aticonfig=Gibba atiports=2

and it will run Chimera at 1920x1080x32 but OSX defaults to still mirroring and at this 1440 resolution.

I think this is because of the lame incompatibility of the 6950 in Snow Leopard due to no drivers. Is there any way to get a 100% usable version of OSX on my system? I'm getting versed in this new frontier but I'm still quite unexperienced.
