This shouldn't be a problem. Libreboot D16 is even used in production
(e.g. vikings) and is stable. Lack of microcode updates doesn't cause
thermal issues on these CPUs, and virtualization still works on the
CPUs that we use.

I work with Timothy Pearson, the person behind TALOS, who also ported
D16 to Libreboot. The Libreboot D16 is about as powerful as the TALOS.
The TALOS campaign seems to be failing (the campaign hasn't budged in
about a week, with only 12% funded and 13 days left) so Minifree has
started offering D16 as an alternative, until we can figure something
else out.
