ah, good - thanks for testing it. I havent seen a lockup on the T60 
either - but it was very sporadic to begin with. (and now we understand 
why: hwclock is running only once per reboot.)

Plus, the real bug has to be found as well: who in the rtc ioctl path 
calls this code with irqs disabled - it's not nice.
