Not, but I found a solution just a few minutes ago...
I was looking for a routine to solve

   A x = l * B x

A,B are NxN matrices, l are the eigenvalues and x the eigenvectors. But 
I've just found out that this is possible with scipy.linalg.eig, which 
supports the "generalized eigenvector problem" ...
