Repeat for anybody who ignored this request the first time.
In current modutils, a module that does not export symbols and does not say EXPORT_NO_SYMBOLS will default to exporting all symbols. This is a hangover from kernel 2.0 and will be removed when modutils 2.5 appears, shortly after the kernel 2.5 branch is created.
Starting with modutils 2.5, modules must explicitly say what their intention is for symbols. That will break a lot of existing modules.
The command below lists the modules that are compiled on your system and will be affected. All code maintainers need to run this against their 2.4 modules and do one of two things. Either export the required symbols (remember to add the .o file to export-objs in the Makefile) or add EXPORT_NO_SYMBOLS; somewhere in the module (no change to Makefile).
objdump -h `modprobe -l` | sed -ne '/__ksym/h;$b1;\:^/:!d;:1;x;s/:.*//p;'
