No, you need to set up the modules in a regular thread. An interrupt routine
can't do IO (get_module will need to read the module library off the disk) or
much of anything else. As mentioned earlier, put the get_module in your
init_driver function and the put_module in the uninit_driver. Save the
pointers to the bus manager module functions (not other kinds of module
functions) you want to use as global variables, so that the interrupt can call
them. Set the globals back to NULL in uninit_driver, so you don't accidentally
try calling a module function when the module isn't loaded.
