Define pain. Mesa3d software rendering will turn over wine. Now if you turn over a game too heavy you will basically run out of CPU. Other issue I have seen no work to add fully functional 2d support to X11 for the SIS cards either. http://www.winischhofer.eu/linuxsispart1.shtml#13 760 are known to be evil. So even if the 2d side works you are still going to run into hell.
