Now that most everything is working (sans the crappy TI SD reader) on a good solid kernel, it's time to break stuff by adding powertop and latencytop. Laptop users should play with powertop a bit to find out how to lower their power consumption; latencytop can be useful in debugging lagged or unresponsive applications.
sudo apt-get install powertop
The latencytop patch applies cleanly to 22.214.171.124, and requires CONFIG_SCHEDSTATS be set. Powertop requires CONFIG_TIMER_STATS and suggests many more adjustments while it is running ( though apparently the usbcore.autosuspend advice is deprecated).
On an unrelated topic, now that inttab is gone the settings for terminals (you know, respawn getty and all that) is in tty-specific files in /etc/event.d . Why? Who knows! Maybe they're trying to reduce the AT&Tness of their *nix.
