First, I´m new here and hope you could help me.
 
I´m using 10.8.2 on my Notebook (see HackBook in my signature) with working graphics. I have resolution change and QE/CI, but openGL applications crash.
 
I need to update my Notebook from 10.8.2 to 10.9 or 10.10 because of new iWork Apps. I installed it and everything works correctly except graphics. I have bad resolution and no QE/CI. Under 10.8.2 i used kexts from this guide:
http://www.insanelymac.com/forum/topic/285394-guide-acer-aspire-5738g-ati-version-mountain-lion-1082-possible-troubleshootings/
But I use Clover as bootloader because of iMessage.
 
Of course, under Mavericks or Yosemite the kexts from 10.8.2 are not working. I tried to make my own ATI framebuffer with this guides:
http://www.insanelymac.com/forum/topic/273937-guide-getting-xfx-hd6850-connectors-to-work/
and
http://www.insanelymac.com/forum/topic/252061-mobility-radeon-hd-4650full-resolution-with-qe-ci-working-on-internal-lvds-screen/
but without luck. I got everytime black or white screens. In Clover I use Load VBios; Inject ATI; Inject EDID; AtiFramebuffer: Shrike; VRAM: 512.
 
What I know from my VBios (extracted with AIDA64 under Windows; decoded with radeon bios decode and redsock bios decoder):
Sense IDs:           Transmitter:           Encoder:
LVDS:  07            12                          04
VGA:   01             00                          10
HDMI: 02             10                          00
 
My Device ID is 9553.
 
I tried this framebuffer:
02000000 40000000 0901 0000 12 04 00 07
10000000 10000000 0001 0000 00 10 01 01
00080000 00020000 0001 0000 10 00 02 02
I also tried this ControlFlag part at LVDS:
00010000
 
What is wrong there?
 
I also tried to extract the frame buffer from 10.8.2 kexts, but there is Peregrine used an in the ati_personality.pl output is no Peregrine.
 
Please help me to make my graphics work with QE/CI and full resolution! I need the LVDS and the VGA connector. A working HDMI would be nice but is not so important.
Thanks!
 
PS: My Mavericks install app is 10.9.4, so i couldn't install an earlier version.

PPS: I couldn´t attach my VBIOS, why?
