You sure you want to require 32bpp framebuffer and depth buffer?  You sure
you're running at the right depth?  XF86Config file should have
DefaultDepth 24 under Section "Screen" or the above will not work.
Something to check, anyway.

Note, you can probably set all of those to 1 except for SDL_GL_ALPHA_SIZE
(which should be 0) for maximum compatibility.  No promise it will not
look like crap if someone tries to use it on crappy hardware, but at least
it'll run..
