fglrx is the closed source ATI binary driver. radeon is the open
source driver. You should use one or the other. The fglrx driver can
use either the kernel's AGP support, or the AGP support in the fglrx
driver itself. If it detects kernel support, it will not try to use
its own AGP support. As you have seen, the best way to ensure that the
fglrx's AGP support is used is to recompile the kernel without the AGP

Please could you post the link to the ATI article, and let us know
which kernel/ATI card you are using. Also, do you have the kernel
headers/source installed?
