well, mapping both HAL_PIXEL_FORMAT_RGB_888 and HAL_PIXEL_FORMAT_BGRA_8888 to
DRM_FORMAT_XRGB8888, for example..

tbh I'm not sure what "endianess" HAL_PIXEL_FORMAT_* thinks about, but if
HAL_PIXEL_FORMAT_RGBA_8888 -> DRM_FORMAT_RGBA8888, then it seems odd that
HAL_PIXEL_FORMAT_RGBX_8888 -> DRM_FORMAT_XBGR8888..

just revert the patch to the way it was before.  If you are still getting a
black screen with current mesa then we should debug what is wrong in vmware
gallium driver..
