One approach would be to take one of the unresolved symbols and grep the whole kernel source tree to find which module(s) implements it and then check if the module is being included in the build. Repeat this process until it will load.
find /usr/src/linux -name "*.c" -exec "grep" "-l" "wib" "{}" ";" To list all kernel files containing wib. Or alternatively, use rgrep ;-)
