What bitness is Mountain Lion kernel, because `uname -p` returns `i386`?

Question

I know, the answer should be 64, as Apple dropped support even for their early 64 bit models BUT:

Nathan-der-Graue:~ max$ uname -p
i386

while on the other hand: enter image description here

Could someone please clear this out for me?

You want uname -m rather than uname -p to determine the bitness of the kernel.

$ uname -m
x86_64
