Thanks… That’s good to know.

But does it work in a G5 64-bit machine?

If I understand correctly, that’s the problem with the Nvidia boards — the nouveau driver doesn’t work in a 64-bit environment with the huge page option that is native to that environment.  So Peter’s software change configures it to use the smaller page size which is native to the 32-bit environment, but available for backwards compatibility in the 64-bit environment as well…

Please correct me if I’ve got it wrong.
