No time to look deeper right now but this can most likely be worked around by using -hardenednopie gcc specs.
I've created a modified ebuild based on Sam Hocevar's discussion on PIC-aware Assembly code. Works for me. http://sam.zoy.org/blog/2007-04-13-shlib-with-non-pic-code-have-inline-assembly-and-pic-mix-well Regards, Dw.

Thank you Attila Tóth! Adding mobile@g.o to CC.

Reported upstream. Preliminary comments positive. We have to see what enters git, tho. http://www.bughost.org/pipermail/power/2008-November/001463.html

I don't know how many users are running hardened toolchain on their laptops, but the reporter of the bug probably does, so at least two persons can benefit.. :) Regards, Dw.
Fix is in sys-power/powertop-1.11 as per upstream. Many thanks to Attila Tóth for the patch and Xake for pushing it upstream. mobile@ - will you (or may I?) remove sys-power/powertop-1.10 and close out this bug? No reported bugs in sys-power/powertop-1.11. In fact, this is the only bug for sys-power/powertop. ;)
sys-power/powertop-1.11 in the tree for 30+ days, works great, no open bugs and no response in this bug. As such, sys-power/powertop-1.10 has been removed, closing.
