Original Half-Life and OpenGL triple buffering not working w/Optimus

Once in a while I like to play some older OpenGL games, such as Half-Life (and its related expansions), Oni, and Quake 3. I'm having some issues, and these problems have spanned across a couple Optimus-enabled laptops including an Alienware M11x R2 and Clevo W150HR.

1) Half-Life, Opposing Force, and Blue-Shift cannot be run on the NVIDIA GPU. When added to the whitelist, they default to the integrated Intel GPU, and this setting cannot be changed. This is a bug that has been present in all 265.xx and later drivers. It did work properly with the 260.99 set, but those drivers have the Punkbuster kick issue. Now the games run absolutely perfectly on the Intel GPU, but I should be given the option to run it on the GeForce.

2) For the OpenGL games that do work on the NVIDIA GPU, enabling triple buffering via the control panel causes them to crash immediately upon loading. And yes, I do have vsync enabled. This isn't a huge deal, but if the option is in the control panel, it should be working. This problem has existed across all Verde/Optimus releases.

These issues are not major in the grand scheme, and the games do actually work in some form or another, which is more than a lot of Optimus users can say for stuff they're trying to do. But if anyone has any workarounds, I'd love to hear them.
