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.
