I assume you're compiling git as 32-bit executables on your G5.  I
don't see any reason why the git binaries would need to be 64-bit.

Well, git seems to assume it can mmap() the entirety of any file under 
its control, so a 64-bit git could handle larger files.

Still, I'm using 32-bit git on ppc64.

Which is a valid thing to do because git also assumes that a
file offset fits within 32-bit as far as I know.  Each object in
a packfile should also fit in 32-bit offset and the size of one
packfile also needs to be within 32-bit offset.  I was unsure if
the last limitation would cause problems in the real life but we
will see in a couple of years ;-).
