Redhat use different FIPS validation process for OpenSSL. You could 
extract fips patch from source package.
Impact is not only for source code. Build process has to be updated as 
well. Red Hat is based on "fipscheck".

You could try with my version of secure shell. It include OpenSSH but 
adds support for public keys algorithms based  on X.509 certificates 
support and works with FIPS enabled openssl.
It should work with OpenSSL build with FIPS module , RedHat or Solaris 
openssl fips enabled library either in fips mode or not.
