It's not really "which steps" but rather "which chipsets/drivers support 
it".

You can only have opengl over the framebuffer with the free DRI drivers, 
and even then it requires some hacking, both on the driver and on the 
SDL side.
It used to work for me on a radeon 7000, it doesn't any more, but here's 
the SDL patch :
