Your config contains an error for the HD4x00 cursor memory patch; you incorrectly entered:

framebuffer-cursor        00009000        STRING

when it should be

framebuffer-cursormem        00009000        DATA


Probably proves you don't need that patch.... I invite you to consult the WEG manual for guidance on the syntax of framebuffer patches.


Then watch out with Big Sur and that MBP11,1 SMBIOS. Better to switch to MBA6,2.
