I know this has to be simple and I want to move away from the Radeon driver.  One last thing, I did a lsmod after building only the ATI drivers and I found neither the Radeon nor the Rage drivers installed.

I think there is some confusing here.  In the kernel there are radeon
and r128 Framebuffer drivers.  These are separate from the r128 and
radeon drm drivers that are also in the kernel and Xorg which is in
userspace.  Unless you need a hi-res console there's no need to
inlcude the r128 or radeon framebuffer drivers in the kernel.  The drm
provides secure access to the GPU for things like 2d and 3d
acceleration.  It's used by Xorg and the 3D drivers.  The xorg 2d
driver does not need the kernel framebuffer driver to operate.
