If necessary, it also works without tools.
The linux kernel has the symbol module_list, which contains a linked
list of all modules. You can follow the linked list until you find your
module. Take the address of the struct module list entry (!) and add
(size_of_struct+4). Then you get to the start address of your module.
E.g.:
&struct module = 0xc100b000
size_of_struct = 0x60
=> .text = 0xc1000064
