Hello guys, i have a compaq cq42 notebook which i recently just installed yosemite on it. And I'm having problem with the graphic card which is a ATI Mobility Radeon HD 5430. Back in mountain lion and mavericks I'm having no problem at all by just editing the ati kext info.plist under cedar from 0x68E01002 to 0x68E11002. But in yosemite its a different story. I have edited the info.plist just like i did in mountain lion and mavericks but to no avail. After editing i do repair permission and remove kernel cache but to no avail. I even resorted to install clover boot loader and inject a fakeID/injectATI and loadvbios to no avail. I have even try forced edid by replacing the displayproductid-717 to no avail. I hope someone can chimp in and help me as i do need this quite urgently. Thank you very much.

Intel i3-350M (2.26G, 3MB L3 Cache)
