The video drivers for the x3100 are far from mature. The issues you are seeing are just driver bugs. Quake3 only uses very basic features and second a lot of drivers are tweaked to play Quake3 well as most of the time it is the second milestone after 'glxgears' works. Wine uses way more than that. Even opengl apps on Wine can use much more features. In all cases make sure you use the latest Intel drivers as that could help and try to submit bug reports to them.
