>Description:

The patch below adds DRI support for the ATI Radeon HD 4250
which is included on several popular mainboards, for example
the ASUS M4A88TD-V EVO/USB3.

With that patch, 3D hardware acceleration works in games
like crack-attack and 3D OpenGL "screen savers" (xlockmore).
Note that graphics/dri and its dependencies must be built
with WITHOUT_NOUVEAU=YES.

>How-To-Repeat:

The game crack-attack is a good test.  Without this patch,
it is unplayable at maximum detail settings and big window.
With the patch, it works perfectly fine and consumes less
CPU time.
