I'm not sure that's a very useful thing, but if somebody can make a kvm image or something with an old distribution that is known to work with FPU emulation, maybe we should verify that the current code at least works. Because even if we decide that just deleting it is the right thing for long-term maintainability, it would be better if we delete it in a state where it is known to work about as well as it ever did. So that *if* we have to resurrect it, we know that it at least was working at the point where it was deleted. I hate deleting code because it got broken. In contrast, I don't mind deleting code that no longer makes sense to maintain. The two are supposed to be very different things.
