I see only two solutions. First, take your Panther drive to another Mac and do the upgrade there. Or, two, ask a friend with the correct version of Panther to e-mail you the ATI Rage Pro kexts (they should be in /System/Library/Extensions/), which you could copy to your Panther. I'm not sure how well this will work, but it's worth a try. f
