Config is all autodetect, got no xorg.conf. I am attaching 2.6.32 ones and 3.0
ones. Commented Xorg.0.log-* with my "on"/"off" toggles.
The interesting thing is - this error seems to be a little bit random -
sometimes the on resolution is ok, sometimes its wrong - but i guess i should
not try to understand because you are the expert and have the knowledge ;).
Hope the logs helps.

Additional Info - these ones are not generated via Fn+Backlight Switch but are
caused by Fn+F2 (Battery Info); so this has nothing to do with this task -
don't know if i should open another task for those ones or to ignore ...

Looks like some program is listening for hotkey events and trying to
change the mode with xrandr. Older xservers used to add 1600x1024 mode by
default so that's probably where the mode is coming from. I'm not sure why
that mode is getting picked when you hit the backlight key, but it's not
something the driver handles. The driver does not listen for hotkey events.
You'll have to find out what program is handling the hotkey events on your
system. This doesn't look like a driver bug.
