If everything works, you should see something like this in your
dmesg:

agp0: <VIA 8385 host to PCI bridge> mem 0xe0000000-0xefffffff at device 0.0 on pci0
(Note: You won't see this if you have PCI-Express controller.)

and

drm0: <ATI Radeon RV300 Mobility 9600 M10> port 0x2000-0x20ff mem 0xd8000000-0xdfffffff,0xd0100000-0xd010ffff irq 16 at device 0.0 on pci1

When you start Xorg server:

info: [drm] AGP at 0xe0000000 256MB
info: [drm] Initialized radeon 1.16.0 20050311 on minor 0

You can probably want to take a look at this:
