Yes, I think they've taken a different tack since then, though for
programming the ACPI subsystem, because very little functionality is
available via sysfs--just stuff like periphrial ejecting. Or perhaps
there has just been no call for userspace access to ACPI information. I
don't know what the deal is.

This is the interesting part. Shem, is this the same I/O port used by
HDAPS and friends?

(Unfortunately there appeared to be nothing interesting in /proc)

You should try loading the HDAPS module ('modprobe hdaps') as well with
batinfo loaded. We need to know if they are conflicting, because that
could lead to unsafe situations if the EC hangs. Don't worry about
damaging your laptop, though, you will know when the embedded controller
hangs (keyboard and mouse quit working, battery monitor applets go on
the fritz) and as long as you are there to power off your machine it
will be fine.

Other than that, I don't see anything else that you need to do. Unless
someone else chimes in with something, you can go back to Ubuntu. Thanks
for being the guinea pig on this. :)
