Cool! The key question though, when you switch to Intel graphics does the power consumption drop or is the ati card still on?Have you checked with Powertop?
Powertop shows the power consumption goes down by some 5 watts.

It works perfectly for me, i was even able to switch between both
cards while
running Linux!
Is this described somewhere, or could you tell us more about how to do this? How to switch to ATI without going back to BIOS? Do you switch the framebuffer console on the fly as well?
When i have the time, i want to write a kernel module that can
switch between
the cards via /sys interface and a little script that takes care about
xorg.conf.
Sounds like a plan. I was in contact with the developer of acer-wmi, and he said he'd rather see this functionality in a separate module as it's not specific to Acer. (I also informed him of the "configuration", "backup" and "powersave" buttons not working.)
