for 2.6 kernels you need 3 things for agp and drm:

1. motherboard agp chipset driver.  this is a driver for the agp
functionality on your motherboard, if your motherboard is nvidia, use
the nvidia-agp module, if it's via, use via-agp, etc.

2. agpgart

3. radeon drm

Both 1 and 2 need to be loaded before 3.

check your kernel log or dmesg to make sure the agp modules and drm
load properly.  hope that helps.
