Bug Description

After patch patches/226_fall_back_to_autoconfiguration.patch got included and applied at the package, the driver fallback for ARM stopped working because of the natural load twice behavior.

As the first load is not needed (Xorg will later load and validate the driver, having fbdev as a safe fallback), we should remove it to avoid Xorg loading it twice and invalidating the driver because of the second load error.

With this bug is not possible to use the PowerVR SGX driver for OMAP 4 without forcing the load with a xorg config file.

  * debian/patches/111_armel-drv-fallbacks.patch:
    - Avoid loading the driver to test if it's available. Xorg will later load
      and validate the module, and if it's already loaded it'll trigger an
      error and invalidate the driver (LP: #959928)
