Can't the chip do guardband clipping? I thought all radeon chips (starting from
r100) could do this, regardless if they support hw tnl.
I could be wrong though (and I wouldn't know how large the guardband would be,
and certainly draw's handling of guardband if you enable it is a bit lacking,
since hw has fixed limits whereas draw will use a guardband twice the size of
the viewport).</pre>
