I once would have agreed with you...until I discovered that the stats clock behaves strangely on my ASUS motherboard - it stops when it loses an interrupt (or one isn't properly acknowleged). I think this is caused by me using DUMMY_NOPS in my kernel [the only thing I can see that would affect the RTC]. I need to investigate further to be certain. -DG
