    Default That's not what I meant.

    I'm not having a go at the Mesa developers. The problem is just that there is a crucial piece of HyperZ missing that prevents it from working properly, so that many "bugs" can be fixed simply by turning HyperZ off.

    And without intervention from ATI, this is not going to change, so it's a bit galling for an ATI representative to sing the praises of the Open Source drivers.

    I did a bit more digging and found that we seem to have stopped using the X12xx names in favour of "690" (desktop) and "690M" (mobile), so having two device IDs is correct after all.
