We have tried the branch above and while it does make it better and usable
in 16bit mode, 8bit is still missing (no wonder as it does not have that
implemented but the AmigaOS driver only allows 16bit and 8bit with the
sm501 device this is used in but probably that's not important when 16 bit
works). Even in 16bit more there were some graphics problems seen but that
may need some more checking to make sure it's not some other change as the
report was not clear if that worked before. I've asked to check the
https://gitlab.freedesktop.org/pixman/pixman/-/merge_requests/71 next to
see if that would work better.
