i got my 15" MBP C2D new in Feb/March, and not once has the battery
info in /proc/acpi/battery/ stopped reporting values..until now. i've
used Linux 2.6.{18,20,21,22}.

with Linux <2.6.22, i *rarely* suspended to disk or RAM because i had
issues with the touchpad. however, when i did, i can't recall a single
instance when the battery info didn't persist.

when i first noticed that the battery info had disappeared, i thought
that rebooting or shutting down would fix it. unfortunately, neither
has helped.

i just booted into MacOS X and confirmed that it's able to query the
battery for the proper info. i then rebooted into Debian and voila,
the battery info's back.
