Yes, this means that DRI and DRM are not being initialized. I had the
same problem, but I can't remember the exact steps I took to resolve
it. I beleive you need to load the module 'agpgart' if it is not
already built into the kernel, and then load your agp chipset module
'via-agp' if that is the correct one.

I'm not sure :) But make sure you did a make modules_install as root,
that should set up the module dependencies properly.

After you have loaded the module, check the output of  dmesg to see if
it successfully detected your chipset. I get something like:

agpgart: Detected AMD Irongate chipset
agpgart: Maximum main memory to use for agp memory: 176M
agpgart: AGP aperture is 64M @ 0xe8000000
...
agpgart: Found an AGP 1.0 compliant device at 0000:00:00.0.
agpgart: Putting AGP V2 device at 0000:00:00.0 into 1x mode
