I would like to ask for a little help.
I have a "special-edition" HD5670 card. To be precise: VTX3D Radeon HD5670/1GB
System Information here:
As you can see it has a custom device id 68B9
which not the standard for HD5670 cards: They use 68D8 usually
This wasn't a problem for me in OSX 10.7.x cause I just added 0x68B91002 manually to my ATI5000Controller.kext repaired permissions and it worked perfectly with Hoolock personality added to org.chameleon.boot.plist
Now in 10.8 there's no info.plist in the ATI5000Controller.kext
I did researches and found info about the newly introduced AMDRadeonAccelerator.kext
I opened it up and edited its info.plst under the Juniper part and added the line 0x68B9 to it (I know 5670s use Redwood but GeekBench says it's a Juniper card)
So I added the line, repaired permissions booted up with GraphicsEnabler=Yes (I use ErmaC's latest boot loader).
With -v it boots the system but the screen stuck at showing the log. If I type in my password (blind - no GUI) and then I press CMD+Shift+3 it takes a screenshot(I can hear the sound) so it means the system boots up properly but it messes up something with the vga.
This is everything I could find out by myself.
Do you have any idea what should I do?
My system spec are:
Gigabyte H61M-D2-B3 (I'm using pre edited DSDT - works well)
Intel i3 2120 CPU
VTX3D 5670/1GB vga
Sorry for talking so much but I wanted to tell you everything and maybe it might help other people later in the future too.
