>From kernel/module.c , in SYSCALL_DEFINE3(init_module..): the line load_module(...) loads your module into the kernel, and the line do_one_initcall(mod->init); calls the init functions. So I think if you set a break point in between these lines, you should be able to get the address of text section etc just in time before the init functions is called, using p modules or something. -Joel
