The issue really is that the raspberry pi people do not produce a pi
kernel or firmware in 64 bit at this time. They are not expected to do
so officially either.
As KB said, we already use their (the pi project) kernel and firmware
(rebuilt by us) and our userland. But they don't provide 64 bit versions.
