Well, I have to say that Transmeta CPU's aren't exactly known for their
openness ;)

Also, the native mode is not very pleasant at all, and it really is
designed for translation (and with a x86 flavour, too). You might as well
think of it as a microcode on steroids.

If open hardware is what you want, FPGA's are actually getting to the
point where you can do real CPU's with them. They won't be gigahertz, and
they won't have big nice caches (but hey, you might make something that
clocks fairly close to memory speeds, so you might not care about the
latter once you have the former).

They're even getting reasonably cheap.
