Hi,
yes - usually the board supplier just needs to rebuild the Mali binary drivers, correctly specifying the memory region the board can use for the framebuffer device. This can move if the kernel is reconfigured as it may change how many peripheral drivers are included - and each driver may be reserving some of the system memory map for its own uses.
Mali will only direct-render to the framebuffer if the driver has been told it is permitted to write to that memory region.
HTH, Pete
