about the same 280 wakeups per second between 2.3.38-8 and 2.3.38-9 from linux-image-2.6.38-9-generic_2.6.38-9.43lp760131v201106060906_amd64.deb. however ACPI estimated power usage goes from ~19W to 17.4W

I also tried 2.3.32-33-generic from the ubuntu pool, and got 18.4W with 320 wakeups per second.

In all cases I started power top, enable everything it suggested and wait for gwibber to finish syncing after boot. I had emacs, firefox (open to simple pages), and gnome-terminal open, plus whatever starts by default in 11.04. Once top showed the system mostly idle I pulled the AC to get the ACPI power usage estimate.
