the kernel driver for the cv64/3d will need more changing to allow for
Z2 support (what board address range is mapped where when you mmap the
device), but otherwise drivers can do as they wish... they "directly"
access the hardware.

However, when this is done, Xamiga will have to be changed at the same
time

Its a completely different chip and, more important, chip mapping on the board,
so its just out of question. You neet the appropriate chip docs.
