In the Insanely mac forum I found an ati framebuffer file that finally worked for me, its Dong's Radeon HD.kext. If you google Dong's ATI or Dong's Radeon HD you should find it there. Its a 32 bit driver so my iBoot shows 32 bit mode not 64 bit. I have full audio, full wireless, full ethernet, haven't tried the built in bluetooth yet, i get 1920 x 1200 x 32 graphics.
I don't know what else to try..maybe someone with more multibeast experience can help me. I am thinking its probably a graphic card problem. However, I do have ATY_Init in there and it doesn't affect the Dong's RADEON HD kext. Maybe the two magically allowed me to boot this in iBoot. Anyway, I will attach my DSDT.
I can only boot my laptop up in iBoot so far. Enclosed you will find my DSDT.AML file, I used a DSDT Editor that was also in insanelymac.com and it extracted it and patched it with no errors and a few warnings. Let me know if i can further optimize this DSDT file.
UPDATE: I went back in and removed the ATI_Init Kext and the ATI x2000 kext and ran multibeast with USER DSDT settings and the RADEON HD Kext and I get full resolution at 32 bit. Now I need to find a 64 bit compatible driver. It boots up from the HDD!
My Install: Chameleon 2 RC5, User DSDT, Voodoo 2.7.2 HDA, Voodoo PS2, (manually installed Radeon Kext in System/Library/Extensions folder
Extracted, patched and compiled my DSDT with DSDT Editor in Insanelymac.com.
