I believe you reported issues due to different page size for the CPU/GPU.
Have you tried nouveau recently, there has been a handful of patches
on the topic since your report.

Alternatively, it would make sense you rebase, cleanup and merge your patch.

That was a problem for the G5s. There were other issues for more
ancient machines with older nVidia GPUs. Additionally a lot of those
Apple machines don't have a BIOS ROM to get the various tables from.

At this stage unfortunately I don't have access to most of that HW to
test with anymore. I do have one G5 I might be able to dig out of my
basement this week to try out.

In any case, digging out that patch should be useful as powerpc64 is
still 64k pages :)

Cheers,
Ben.
