Rick,
The FreeBSD Foundation maintains significant resources in the various
FreeBSD clusters for the purpose of testing FreeBSD on a variety of
hardware platforms and scales. Why don't you ask them for access to
some of these systems so you can run tests of your own? I don't think
it would be hard to come up with a test plan that would cover at least
the most common cases.
