 You have to do this procedure every time you boot your system, yes.
You can install a second kernel to your system, it will be easier to 
boot on it each time than with a rescue cd, you can even use a little 
script to automate that, but the best method is to modify the bios.
Even if your version isn't R1180C3, the method I described could work, 
you only have to stop if any error occurs with python scripts ;)
Else you can try to get help here :
