Handling packages with SSE extensions

Hello all,
I'm working on a package for ATLAS (Automatically Tuned Linear Algebra
Subsystem). On i386, it can use SSE, SSE2 and 3Dnow. How are programs
handled that use these extensions? Are there other packages that would
make good references? I have gmp installed on my system, and I see that
there are libs with identical names in /usr/lib and /usr/lib/sse2. Is
this the standard way of dealing with this? How does the system load the
correct libraries? How does rpm/yum deal with choosing what to install?
