You probably *are* experiencing character loss. I still haven't fixed 
the problem that low-level EC access can sometimes lead to lost 
interrupts. I've tried to mitigate the problem by putting a 1ms sleep 
after each access, but that isn't perfect.

However, I'm glad you're getting consistent results with the i2c method.

Nah, but I'll have a dig around.

BTW, a warning for those with Smart Batteries (or, for that mattery, any 
LiIon battery): you can damage your battery by running it all the way to 
empty. I kind of knew about this already, from stuff I'd read on the 
internet; but I got a nasty reminder last night. I ran my battery to 
empty, to see which smart battery alarms went off (disappointing; there 
were no alarms triggered, and only a single warning flag was set ~5 secs 
before empty). Unfortunately, this procedure led to the loss of ~3% of 
my battery capacity.

Maybe when I get the in-the-works SourceForge project going, I'll set up 
a PayPal donation fund for a new battery :).

cheers,

Rich

PS Overnight, I got a number of new DSDTs from various people; I'll be 
fixing these today and posting them on the website.
