Radeon Driver not loading?

[Seraphim9]

I was having some odd graphical things happening on my laptop at boot so I checked the KInfoCenter and noticed that next to the Renderer line it indicated 'Software Rasterizer'. I did a little research and discovered that this is not a good thing as it means that the radeon driver is not loading. Does anyone know how I can get the driver loaded properly so that the hardware not the software does the rendering? Below is the terminal response to glxinfo | grep render.

direct rendering: Yes
OpenGL renderer string: Software Rasterizer
    GL_EXT_vertex_array_bgra, GL_NV_conditional_render,

I have a 17' PowerBook G4 1.5 Ghz with an ATI Mobility Radeon 9700 AGP 64MB as far as it working before I'm not sure. This was the first time I checked. I will take a look at the links provided. Thanks.

Got it working for now. I have tried adding a few command lines at yaboot as recommended by the PowerPC faq and the following has given me 3D acceleration and loaded the open-source radeon driver.

Linux radeon.modeset=1 video=offb:off video=radeonfb:off radeon.agpmode=-1

Here is the link that helped solve this issue for me. It's under the Configure Graphics section. You can make the yaboot parameter permanent but I have not tried this yet.
