[openssl-users] OpenSSL FIPS (0.9.8) coexisting with non-FIPS (1.0.1)

The scenario that we're contemplating is having FIPS based on 0.9.8?? coexist with 1.0.1?? so the remapping at runtime would have to account for api differences within the two. This was really the upshot of my question.
But I think I'm still a little confused about the FIPS-certification of OpenSSL 1.0.1??, I remember reading that some of the FIPS power on self-test requirements precluded a general FIPS certification, is that the case? What is the status of FIPS OpenSSL certification? (Is this written up anywhere?)
Thanks again ... N

If I'm following here, you want to deploy something that uses OpenSSL
1.0.1 either with or without the FIPS module, as decided at runtime.
That's a common enough scenario: those customers who must use FIPS will want that, all others either won't want or don't care about FIPS (some of them very specifically won't want it, for understandable reasons).
You don't need two separate builds, a single build of one set of libraries can be used for both purposes. We call that the "FIPS capable"
OpenSSL: build openssl 1.0.1 with the "fips" build time option in the presence of a FIPS module. You wind up with the same libcrypto and libssl libraries that you know and love. That one set of libraries can be used for either purpose: use them without calling FIPS_mode_set() and they behave like stock 1.0.1. Call FIPS_mode_set() to enable the FIPS module of operation and your application will automatically be using the embedded FIPS module (with non-approved crypto operations disabled).
