Yes, remove atindrv.kext and fix permission.
Did you get your card working??

I just back from the "grey screen", seems it does work for me or I did wrong.
There are 6 files
ATIRadeonX2000.Kext
ATIRadeonX2000GLDDriver.bundle.
ATIRadeonX2000VADriver.bundle
ATIRadeonX2000GA.plugin
ATINDRV.kext
GLEngine.bundle
I put first 4 in the "extensions" folder. According to the original pack, the last one should be put in "/usr/libexec/oah/shims/", but I can't find the path.
BTW, in ATIRadeonX2000.Kext/info.plist , I can't find where to modify the VenderID and DeviceID.
