The point I was making in my email was not about the use of FIPS
randomness tests. The FIPS randomness tests are not very important.
The point I was making was about the use of a hardware security module
to store really high-value keys. If you have a really high-value key,
that key should never be stored on a Linux server: standard advice is
that it should be generated on a hardware security module (HSM) and never
leave the HSM. If you are in charge of Verisign's root cert private key,
you should never let this private key escape onto any general-purpose
computer (including any Linux machine). The reason for this advice is
that it's probably much harder to hack a HSM remotely than to hack a
general-purpose computer (such as a Linux machine).

Again, this is probably a tangent from anything related to Linux kernel
development.
