Rather than just those alone, there are cases where bttv (random writes) 
overwrites the EEPROM contents on some DVB cards as well. There have 
been quite a lot of reports on the linux-dvb ML earlier. Many people 
thought that it was the hardware just went up in smoke, but it wasn't 
the hardware.


IMHO, a random write should never be attempted.
