AHA! So I suppose then THIS is also the reason why km (experimental ATI
capturing v4l module) doesn't mix with DRI on r128 (i.e. it causes lockup when
X tries to do 2D-accelerated function). I read that CCE and DRI didn't mix
well yet, but only now thnx to your email I realized this is the cause of the
lockups I've been experiencing.
