Hi,

I am a mostly happy user of Gentoo Linux (under Bootcamp, x86_64,
kernel 2.6.19 + mactel-patches-2.6.19 (revision 81), ATI proprietary
drivers 8.30.3-r1) on a Macbook Pro C2D.  My kernel config is
available [1].

"Mostly happy" means of course that most things work as expected.
Suspend to RAM in particular seems finally reliable since the recent
upgrade to 2.6.19 (and the new set of mactel patches) three days ago,
and the new pbbuttonsd [2] handles all the keys and adjustments just
fine.  Some things do not work to my liking (like everybody else I
have relatively poor battery life, I could not yet find out how to
make the external display work, and the Wlan is not yet supported by
anything in a 64-bit environment).

Anyway, I will come back with these problems later.  Right now I am
trying to seek tips and maybe a solution to my currently most annoying
problem, namely battery information:

My machine 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 [3] 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.  At the
very least, does somebody knows who is the culprit?

Supposing now that I get rid of Bootcamp, one question is whether I
get my battery information back (as asked between others above), but
then another question is will this impact negatively anything now
working (most significantly the proprietary ATI drivers and/or suspend
to RAM).  Advice for people who tried all of this is appreciated.

Many thanks in advance for any information on the matter.

Cheers,
Stefan
