Thank you for the additional files. It looks like the driver of the card does not support certain opengl features spiftacity seems to rely on. I'm not an x driver export bug it seems this is a bug in either the driver or spiftacity. I will look for upstream bugs at the freedesktop.org bugzilla and see if they know of this problem already.
