As a less last-resort option, you could just write a separate ctypes wrapper for some single-precision FFT library (FFTW in single mode, say), and provide it as singlefft. This is of course not as nice as Robert Kern's suggestion of making single-precision FFTs an integral part of numpy, but it would solve your problem and be fairly straightforward.
