I always use xcode for plists, so as to verify syntax is valid...
IOreg3 is too buggy to be of any use.

Looks ok, although you haven't implemented GPU power management or backlight control...

You could try injecting EDID (as I mentioned before).

Also, EHCIacquire is not a kernel flag... but rather a boot flag specific to Chameleon.

I created a DSDT as in the guide and got backlight control back.

Injecting EDID - is it enough to select inject in clover graphics injector menu ? If so I already tried with no success :(

Yes... no further ideas. Maybe IGPU memory window as configured in BIOS is mismatched with framebuffer assumption. Try different ig-platform-id values and/or framebuffer connector table edits.
