As far as I know, at least the basic SDL graphics stuff should work
just fine anywhere you can expect to get a normal graphical program
running. Basic OpenGL stuff is also doable with just a plain vesa
video driver, but of course it'll be quite slow unless you have
hardware acceleration.

I don't think you need the radeonfb driver for anything SDL related. I
think the SDL framebuffer usually refers to the pixels inside the
window that SDL creates for you.
