Accel. OpenGL on SDL Platforms

I was wondering which of the platforms supported by libSDL have hardware
accellerated OpenGL contexts. Obviously, Linux x86, Windows, MacOS 9,
and MacOS X do, but what about the others?

I know FreeBSD has most of the DRI drivers and are getting native NVIDIA
ones too. I’d have to assume Solaris and IRIX probably do (as they are
often used as CAD workstations). What about Linux PPC, the other Linux
hardware platforms, BeOS, PS2, and QNX… or any other platforms under
development. Amiga???

I am asking because I am trying to start a game porting house and need a
list of platforms that I could get a 3D game to compile under using SDL.
