One piece of advice I found is this:
I am not sure this will be any help to you as the post is quite old. You would have hoped they might have improved the driver by now but maybe this advice is still relevant.There is a bug in the Intel video driver for the older intel 830 and 845 integrated video cards that are used on laptops like the IBM R30. Desktop effects with compiz will not work on those chips and will freeze the system. For new installations, please install using the safe graphics mode (press F4 in the startup screen) on these systems and disable desktop effects via System -> Preferences -> Appearance, clicking on "Visual effects" and choosing "None".
Sorry I can't be more help.
