So don't confuse devs by doing so.

You sure about that ? I remember this helped with GPU lockup and i
also seen fglrx aligning IB.
Yeah, pretty much. Well I searched for halve an hour for the
corresponding IB alignment in mesa/the CS ioctl until I finally figured
out that there isn't any.
So IBs submitted by usermode aren't aligned in any way.... So it really
seems to work fine and I couldn't find any reason why we should align an
IB for the GFX ring in our docs also.
Christian.
