you as developer can do a grep on the kernel source for
EXPORT_SYMBOL ...

and the module loader will also tell you if you use a symbol that's not
exported....

but realistically if you use the standard APIs you're not going to find
symbols that aren't exported... what kind of driver are you trying to
write?
