ATI all in wonder 9600xt + running dual monitors(newbie)

My problem is that i cannot get knoppix to recognize that there is a second differnet monitor. Right now i have the same thing displayed on both monitors(I'm literally seeing double). I guess what i mean to ask is one: can I run dual monitors. two: if i can how would i go about doing it. I did find drivers on the ATI site but when i try to install them I have no space( :?: for the image i alocated a gig and a half ) . I thought that is i created a knoppix disk image that would take care of the problem and it didnt. First before anything i want to know how can i install those drivers. :?:
