What system are you trying to run it on?? I have Tiger in my Digital Audio and it originally came with a Rage 128 AGP and it worked fine for me. Keep in mind that the Rage doesn't come with a lot of memory, so you won't be able to do 3d with textures. When I tried using it with EQ Mac, I could see all the objects, but they were all blank because there was not enough memory to load in the textures. I got a Radeon 9700 flashed with a Mac ROM and all my problems went away.
