X-Plane Demo fails to start with the following error:

drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See
dmesg for more info.

Corresponding `dmesg' snippet is as follows:

[53540.965945] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

The free installer is available through the following address:

The `radeon' driver is in use. The xorg.conf is not used in my system. The
video card is ATI Mobility Radeon X2500 aka X1600.
