    Well, they didn't at any point say they want to opensource fglrx, did they? Besides, who are they to deny radeon developers the pleasure of yanking their hair out in frustration while trying to figure out how a memory manager should work.

      Because it'd probably have to be 99% rewritten to fit in with the OSS API. Also because they're paranoid that nVidia will just rip it off.

        Hasn't nVidia had a kernel memory manager longest of all the drivers? You'd think it's so well optimized they wouldn't care what their competitors do.

          On the other hand, maybe VIA would... their drivers on any OS make fglrx look like NASA software by comparison.

            The closed source memory manager is designed around a completely different driver stack, all parts of the stack (2D, 3D, etc.) have have to be substantially rewritten to use it.
