With my A10-5700 ARUBA I have a problem running 32bit applications under 64bit
kernel (not tried 32bit kernel) while 64bit applications are fine. Essentially
the X server crashes with a segfault after the following messages;

[CRASH]

System is running;
- Linux 3.9.0 with all radeon patches from drm-next-3.10-2 (but problem occurrs
with standard Linux 3.8 and 3.9 too, though unknown for earlier kernels)
- Current Mesa git head for both 64 and 32 bit (definitely no old libraries).</pre>
