I don't have the slightest of an idea what the different pagesize are
good for. I would like to have a working operating system, and if the
Nvidia driver nouveau doesn't work I don't have such a working operating
system.
Frankly, I don't care about the pagesize. I only had problems with
switching between 4K and 64K and I would be glad if the Linux
distribution for PPC and PPC64 would use the appropriate one for the
hardware. Since most ppc64be systems are most likely Power Mac G5s, and
half of those machines use Nvidia cards, this should be a heavy argument
for using a compatible configuration.
Anyway, I found this:

I don't understand much, but Linus Torvalds seemed to think that 4K
pages was a good idea.
Just my 2¢...
