Problem with GraphicsEnabler=Yes Notes about system: running M17xR3 with switchable graphics, intel IGP 3000 and ATI 6970m. Issues: 1. Does not work with intel hd 3000 GFX. Instant black screen on boot 2. When using only 6970m (IGP Disabled), bootloader hangs on "ATI card posted, reading vbios from legacy space" the card is used in iMac systems, and dev id natively exists in ati6000controller.kext I require elodea framebuffer. I give you dev IDs here: IDs for 6970m: Vendor- 1002 Dev-6720 (exists in ati6000controller already!!!) subsys-04BA1028 6970m requires framebuffer Elodea! Please help fix! Card is recognized by OS X, but makes graphics garbled and hazy. I don't think proper framebuffer is loaded.
