Well, the "is sys_call_table exported" stuff might actually work right.

Well, if nothing else is including it, it's needed. Are you using a
versioned kernel? Without this, you should get a module with refs to
sys_call_table and not sys_call_table_R12345678, which means the kernel
module just won't load, unless you use insmod -f. We don't want people to
use insmod -f.

Is something else including it now?
