What about doing it not as a workaround for broken hardware but to make it more easy to show that the hardware is broken? In theory I know that I'm probably getting bit errors and that's bad(TM) but if a cat /proc/bit_errors showed me that I got at least 5 since boot I would be much more motivated to do something about it.
