Using kld functions in other kld's?

[Mrzh]

I'm trying to access one kld's functions from another kld in FreeBSD 5.3.
Even though I have non-static functions in my first loaded kld, subsequent kldload of
another kld that refers to those symbols gives me "link_elf: symbol blahblahblah undefined".
I was able to do this kind of thing in FreeBSD 4.x before.

Is what I'm trying to do possible in FreeBSD 5.3?  What could be source of the problem?
Thanks very much for any reply!
Paul.
