The problem here is that what we desperately need first is a method to 
restore the original EEPROM contents after it gets corrupted (David Airlie 
has, sadly, apparently bricked his notebook while trying to do so). 
Without this, we can put a lot of debugging/protecting patches into the 
kernel, but we won't be able to succesfully verify anything, because 
testing wouldn't be possible.

Added Jesse and Karsten to CC, as they are working on such a tool right 
now, as far as I know.
