Hello everyone,

Powertop reports "no ACPI power usage estimate available" with x86_64
kernels 3.0.6-1 and 3.0.6-2.

Downgrading to kernel 3.0.4-1 restored power estimates.  Older kernels had
always worked in the past.

Processor is Intel i3, quad core, in a ThinkPad Edge 14 running Gnome 3.2
fully upgraded daily.
