I've fixed the script as included below and it works very
well. However I now have to boot into Adam's switch status checking
kernel every time I boot the computer which is tiresome and so close
to good enough. 

I understand I can hack the BIOS to set the register according to the
switch position at startup, but I really don't want to do that. Is
there any other way to ensure that the switch position is honoured at
boot time?

Thanks,

Simon
