Not yet. To fix it, the r600g driver needs to be adapted to changes in the way the Gallium3D infrastructure deals with big endian hosts.

Hi Michel, Thanks a lot for your answer. :-) We had a problem with wrong colors in SuperTuxKart 0.8 last year. The Irrlicht guys have released a little hack for Irrlicht on Linux PPC (http://irrlicht.sourceforge.net/forum/viewtopic.php?f=7&t=48577). They told me that is a driver bug, and that workaround costs performance and RAM. Unfortunately this workaround isn't suitable for Mesa 9.2 and higher. At this time we have to install Mesa 9.1.X and lower on new Linux distributions like Lubuntu 13.10, Debian Sid etc. It would be nice to solve this issue because we don't need the workaround in the future.
