Søren, 

for this kind of problem you could also use bim.
attached is an example script to solve a particular system
of 2 semilinear 2nd order ODEs with two-point boundary conditions.
If you can provide more info about your specific problem I can help 
you adapt the script to your needs.


HTH,
c.

P.S. this example was written quite quickly I'm sure it DOES contain bugs ;)
