If it is a laptop ,then i believe it will indeed be an ati mobility.
all i can find about graphics card specs is this.
Card 16- Bit,Graphics Card 64 MB ,Graphics Card (Direct X 9 Compatible).
Unless it specifically says that this card is not compatible on the game case,then i would say your card can run it.
You could always download the demo first to see if it will run as it,s only 40mb.
