Question on power consumption of zen-updater and opensuseupdater / kernel - powersaving options

Dear listmembers,
when trying to optimize openSUSE 10.2 on my X60 (please see 
http://www.thinkwiki.org/wiki/Installing_openSUSE_10.2_on_a_ThinkPad_X60 for 
my findings) I stumbled over some "Ungereimtheiten" - please translate 
whoever can :-):

1.) Both zen-updater and opensuseupdater continuously keep loading the battery 
through wakeup events - IMHO one event every hour should be more than enough 
for such a tool.

2.) The kernel lacks several settings for optimizing the power consumption, 
these are specifically:

CONFIG_TICK_ONESHOT=y
CONFIG_NO_HZ=y
CONFIG_HIGH_RES_TIMERS=y
CONFIG_USB_SUSPEND=y

For powertop:
CONFIG_TIMER_STATS=y

Why aren't those activated? Stability issues?

Activating the kernel parameters and playing around with powertop brought me 
from ~15W power consumption in battery operation mode down to ~10W (lenovo 
thinkpad). This is something other laptop users might want to profit from.

Any comments? Should I open bug reports for these?

Thank you very much,
take care
