Add powersave=0 into kernel line solves flickering problem of i915's. However, it may cause random lockup of X(on booting) at least on my laptop, never happen after removing this parameter. 2.6.33 didn't solve this problem either, but I still cannot find a bug report tracking this problem, any clue?

If I remember correctly, the .32 series has a bug with Intel cards that causes screen flickering and the patch that corrects this was only merged in the .33 series
During the .32 series I tried a few arch releases and they all caused the flickering in my laptop, so I rolled back and went from .31 to .33 when it was released.
For .32 did you try setting i915's powersave parameter to 0?
