When modules were first introduced, all symbols were automatically exported. For kernel 2.0 compatibility, a module without EXPORT_NO_SYMBOLS actually exports everything. There are flags on insmod to override this default. modutils 2.5 will remove this backwards compatibility, no module will export symbols unless they are explicitly exported. If you are feeling brave, add insmod_opt=-x to your modules.conf and see what breaks in 2.4.
