I have an Intel MA950 chipset, so I don't need to install any ATI or nVidia drivers
It's not that you don't need
to install an accelerated driver, but that you cannot!
So far as I am aware there are no linux accelerated drivers for Intel graphic chipsets: Only NVIDIA (recommended) and ATI, so I think you are out of luck here.
1] Moan at Intel for them to release linux drivers for their chipsets like NVIDIA do.
2] Do not buy a laptop that doesn't have an NVIDIA graphics chipset.
3] Play games v-e-r-y slowly!
