I am not having this problem with FreeBSD 6.2, which I recently installed on a 
laptop in place of kubuntu and I DID have this problem with the same laptop 
when it was running kubuntu.  I did not change any BIOS settings.  The laptop 
would wake me up with all the noise.  With FreeBSD 6.2 the laptop stays quiet 
if I leave it on overnight.
