What drivers and Xorg to choose?

I have an Acer Aspire One with Intel Atom and I want to run DirectX applications on it. Sadly, my recent try to match up Xorg and drivers with my video card resulted in freezes at startup, then forced command-line mode. I have a built-in Intel chipset, but I don't know what category should I use for it in Mageia Control Center. Also, I don't want to risk another Xorg crash. Also, what drivers should I use for my chipset? I don't want to use Vesa, as it might have issues with DX. Also, does DX work with the open-source Intel driver? I read that Nvidia cards have issues with certain applications when the open-source driver is used.
