It does not really matter. People ignore the messages unless looking
for something specific as you already noticed. Warn seems adequate
because the cipher is weaker than expected but not known to
be compromised. People who care can look up the message. People who
don't care will ignore it even if it's crit.  

Is it worth of trouble to do any driver changes then (open question to
everyone)? I'm not sure it is worth of trouble to add cruft to the
driver code for a warning that will likely be ignored anyway.

If the kernel can reliably detect the affected TPMs it saves the
user the work of figuring out where the firmware revision is accessible
on the running machine and what firmware revisions are affected.

Thanks

Michal
