Yes the RHEL and OpenSUSE rpms for openssl are heavily patched for the
FIPS versions, as is the Ubuntu one. It has been a while but last time I
looked at all of this they were all using very similar patches to allow
the "system wide" FIPS mode rather than depending on the app to
explicitly go into FIPS_mode().

I can look for links, but investigating it involved (for example)
installing the source rpm and then wading through hundreds of patches in
the SOURCE directory.
