acpi works fine for me on AMD64 even though it's masked. I'm not using a laptop, so I haven't tested the battery/ac stuff, but temp is fine. Reproducible: Always Steps to Reproduce: 1. echo "sys-power/acpi ~amd64" >> /etc/portage/package.keyword 2. emerge acpi 3. acpi -t Actual Results: Thermal 1: ok, 40.0 degrees C Expected Results: A crash on compile or run (considering it's masked) I haven't tested ac/battey, but it works fine with an Athlon 3000 on my asus nforce4 board.
Fixed in cvs, thanks for reporting
