I'm sorry, I don't really have any ideas off the top of my head, but
since you're saying you're specifically using MontaVista's CGE product,
I bet they have some folks that can help you out.

There are probably people on the list here who would be happy to try to
help you out, too, but in general the goal of this list is to discuss
issues facing carriers and network equipment providers in their adoption
of Linux.  If you have questions or topics you just want to discuss
along those lines, please feel free to bring them up here!
