we would run into issues with AMD's (and other's) patents, I'm pretty sure
they haven't licensed the patents necessary to implement an AMD-compatible
GPU.

Also, that would defeat the purpose of a lot of what we're implementing
with a Power compatible ISA, having the CPU and GPU be the same processor,
and having an extensible design such that someone could add their own
custom operations on top of our code if they wanted.
