I am having similar difficulty with my rtl8139 modules. I have two
versions I'm trying to get working. I would need to know what the
specific dependencies are to help. 
Did you get Donald Becker's modules? If so you may need to insmod
pci-scan.o as well as the new module to satisfy dependencies. Also
Donald Becker's drivers are well supported by mail lists. Post your
output to the list and someone will know the answer.
Becker's site is at:
http://www.scyld.com/ most likely your driver was originally written by
him. This guy was prolific with net drivers.

HTH,
Brian
