To avoid issue with gradients on ATI card try to inject EDID with Clover bootloader
The recipe is:
Inject EDID with clover, I have found that an editing DisplayProductID-717 causing wrong definition of LVDS. OS X shows it as an external display.
For this you must delete or return original DisplayProductID-717
And configure clover <key>CustomEDID</key> with your EDID
then
<key>InjectEDID</key>
<string>Yes</string>
That's it. This solves my problem with correct connectors and 16bit colors(gradients) on my ATI 5470m
After that you may apply correct framebuffer patch
