Done. Next, will try to add the options mentioned on wiki.

It is not enabled by default, that a problem is.
$ glxinfo | grep -i render
direct rendering: Yes
OpenGL renderer string: Software Rasterizer
It is because needed module for hardware acceleration does not loaded:
[ 7.667868] platform radeon_cp.0: firmware: requesting radeon/R100_cp.bin
[ 7.691511] radeon_cp: Failed to load firmware "radeon/R100_cp.bin"
[ 7.691602] radeon 0000:01:00.0: failled initializing CP (-2).
[ 7.691643] radeon 0000:01:00.0: Disabling GPU acceleration

libGL: OpenDriver: trying /usr/lib/dri/swrast_dri.so
display: :0 screen: 0
direct rendering: Yes
As here we may see, it is software rasterisation enabled instead of hardware.

Correct me, if I am wrong, but I think it is useless until hardware
rendering will be available and turned on.
