a little help in patching DSDT for ATI dev_9555 framebuffer #DSDT

i tried lot's of guides and different methods to get full advantage of my probook 4520 graphic but this mobility radeon hd 4300/4500 still not working.







i tried adding dev id to kext. tried EDID, tried adding it's framebuffer from vbios to shrike in kext.







this is my last try.







i want to add this framebuffer which is already replaced in ATI4600Controller as shrike

the main problem is when i compile original DSDTs it shows lots of errors! and i can't patch! meanwhile i am really not sure where to add codes for GFX!







any help would be really appreciated.
