Did you report this at bugzilla.kernel.org ?

I think I did report it to the kernel developers, but I can't find it
anywhere there. I can't get the bug report system to let me see most
of the bugs I've been CCed on--maybe because they've been closed?

The bug does pop up on Ubuntu's forums at
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/364592 and
elsewhere at http://mindspill.net/computing/linux-notes/acpi/continuous-acpi-lid-events-and-100-cpu-usage.html
.

I do know that this bug stopped being a problem a while ago, and I
think it might be because I applied someone's custom DSDT (which was
customised to solve another problem too, iirc), and I think it was
from bugzilla.kernel.org.
