This has not been my experience. In fact, I usually load it before
pstricks and several other packages.

Do you have a minimal example that exhibits this problem?

Other than the fp/multido problem, I haven't had any other problems
using fp. However, rather than loading the whole fp package I generally
only load the part(s) I need -- and typically that's just fp-eval.

You'll want to double-check me, but IIRC these functions are accessible
from fp-eval. If only load that, instead of loading the entire fp
package, does that solve your problem?
