I have a gentoo-dev kernel, version 2.6.9-r1 on a Compaq notebook, PIII mobile. Every time a compilation is started from emerge kacpid starts to use ~80% of the CPU time. Killing the compilation does not help, and I have to reboot the system. I did not check yet if this happens also compiling from outside emerge, although I would assume so.

Could you please test with development-sources-2.6.10-rc1?
Ok, first I made a double check with gentoo-dev-2.6.9-rc1 by re-emerging gimp, the problem was still there, and in the output of dmesg I found: ACPI: Processor [CPU0] (supports C1 C2) ACPI-1133: *** Error: Method execution failed [\_SB_.BAT1.SEBI] (Node cff0f7 40), AE_AML_UNINITIALIZED_LOCAL ACPI-1133: *** Error: Method execution failed [\_TZ_.THRM._TMP] (Node cff0f2 80), AE_AML_UNINITIALIZED_LOCAL Then I compiled development-sources-2.6.10-rc1 and the above lines weren't there anymore. However kacpid was still doing as before. I should also mention that this is happening while I'm on KDE. I'll give it a try on single mode just to be sure that KDE's power management isn't messing with it...
It's not KDE: I get the same result by booting in single mode.
Could you please file a bug at http://bugzilla.kernel.org for this
