yes i did this before.
I use the hauppauge quad dvb-c tuner and i unload the modul cx2355 before the system goes in standby.
I unload this with my script.
But after a few minutes when the system is back and i watch TV the errors are coming.
Dont know why?
I dont know what modules more to unload. At the moment i unload only cx23885 and card is working
