I honestly don't know.

What we actually need is the TDX module version. I'm not sure how
tightly tied the TDX module is to the BIOS version. I suspect that
they're actually completely independent.

Once we have the specific TDX module version, we can go ask the folks
who write it if there were any RBP clobbering bugs.


Okay, how to get the TDX module version?
