MacBook C2D and battery information (and Botcamp?)

[bruda]

Hi,

My Gentoo (amd64, under Bootcamp) installation on a MacBook C2D keeps forgetting about the battery: Battery information (in /proc/acpi/battery/) comes up fine on boot, stays fine for some hours (time varies) and then disappears (the battery is reported present but every related value is at zero). A reboot does not solve the issue, but booting into Mac OS and back into Gentoo does... for another couple of hours or thereabouts.

Could this be a Bootcamp issue? I have read that Bootcamp is not necessary on these machines but I am somehow hesitant to back Gentoo up and get rid of Bootcamp (lack of time) before asking whether this has any chance of solving things and whether anybody have stumbled on the same and found any solution, so here I am.

By the way, I am using a vanilla 2.6.18 kernel plus some relatively old (December 2006) mactel patches, does it pay to upgrade either?

Many thanks.
