firepro m4000 connector patch

[mtc88]

Hi, I'm having trouble patching the connectors on the amd firepro m4000 in a hp 8570w laptop. The displayport out works and shows 1024mb ram, but I cannot get the laptop lvds to work. If u run the biosdecode app the first connector shows 'FF' at the hotplug id of the first connector.   patching it in the buri framebuffer which seems to match closest doesn't work, or maybe (probably?) I'm doing something wrong? any help would be appreciated!

I tried 00, boot then hangs at gIOscreenlockstate. 05 seems to be the default wanted in the frame buffer(buri)
