Hm ... AFAICT, the intent of the "FIPS mode" in Red Hat's implementation,
and probably other Linux distros, is exactly that thou shalt not use
any non-FIPS-approved crypto code. By your reading above, there would
be no need at all for a kernel-level enforcement switch.

Ugh. But is there any available FIPS-approved library code that could be
used instead?
