Add native game to Steam without buying again?

[AzureKeys]

Oh, well, looking at the hpl.log for that thread, i see that your graphics card is an Intel GM45. As far as i know, that card is too weak to run the game. The Intel website claims support up to OpenGL 2.0. I know you have Mesa drivers for OpenGL 2.1 (which OpenGL 2.1 is what the game requires), but i doubt that means anything if the graphics card isn't designed to handle it. Running it through a virtual machine would not have helped you.

So is there absolutely no way to get a Steam version without paying full price again?
