Interesting. Do you know (i.e., can you say) whether we'll get such an
API in 10.2.7? I'd like to know whether I can move a project to 64-bit
addressing as soon as the G5's ship or not.
(Continuing the disclaimer: yes, I know this is premature. I know I
don't need to know right now. I'm just curious about what to expect in
my near future.)

Not yet. We don't yet have a 64-bit API for the kernel, standard C
library, or other frameworks.
I believe the compiler options in gcc 3.3 allow you to take advantage
of 64-bit integer instructions in the G5, and to do G5-specific
instruction scheduling.
