Well, I tried that and moving the offending statement on top of all the
others, but still no difference.

I have seen this with many different kernels since the first Xamiga24.
I have also tried with standard gcc-options and with -m68040 added.
It seems pretty improbable that the compiler is creating bad code.

Perhaps something with the '040 writeback cache?  Is it enabled in the
register area of the RetinaZ3?

Well, naturally I find this very annoying, but I am currently satisfied
with a software sprite. However, if anyone wants me to try something, go
right ahead and ask. Just don't give me any compiled kernels as I need
very specific screenmodes for my monitor.
