You could also use mpmath to calculate the roots:

It would be good if how to find these was more obvious. Roots of Bessel
functions are pretty common to want to find (at least in fields of engineering
I've worked in). It's not obvious that one would use the Sage interface to
mpmath to compute these.
MMA has these as BesselJZero[] and BesselYZero[]

If nobody beats me to it, when the OpenSolaris and 64-bit SPARC ports are
finished and I can concentrate on other aspects of Sage, I'll look into making
these more easily available.
