same prob w/ my mobility 9600PRO drivers on my laptop.
ATI does not have any laptop drivers....that is so lame!
so the only way i was able to update them was to email the people i bought it from and they emailed me back some strange company who disperses laptop drivers.
and still to this day they have not updated since last April!!
but i'll post a link to where i go, and maybe you'll be lucky and find your model too.
