What scipy/numpy versions are you using? Here (debian sid
linux,fftw-3.0.1):
In [10]: scipy.show_config()
<snip>
fft_opt_info:
libraries = ['fftw3']
library_dirs = ['/usr/lib']
define_macros = [('SCIPY_FFTW3_H', None)]
include_dirs = ['/usr/include']
In [11]: scipy.__version__
Out[11]: '0.4.4.1544'
In [12]: scipy.__numpy_version__
Out[12]: '0.9.3.1863'
In [7]: scipy.fftpack.test(10)

May be these problems are not related to different architectures. So far
only OSX users have reported problems with fftw3. Although there are also
performance problems with fftw3 under Opteron, fftpack tests still pass ok
there.
