This is probably correct.  You need both agpgart AND the specific module for 
the AGP interface on your motherboard (I assume intel-agp is the correct 
one).

I think that is what you need if you use the ATI binary drivers.  I have a 
RADEON 9200, and I wanted to use the open source drivers.  To do that install 

xlibmesa-dri

package, and change the device section to 

Driver "Radeon"

I don't have this in my XF86Config-4, although I do have a commented out 
ChipID (I think from the days when I was having trouble making it work)

Section "Device"
        Identifier      "Radeon9200"
        Driver          "radeon"
        Option          "AGPMode" "4"
#       ChipID          0x4242
EndSection

ALSO in you module section you will need to adjust to remove GLcore and add 
dri an glx

Section "Module"
#       Load  "GLcore"
...
        Load  "dri"
        Load  "glx"
...
EndSection

I think you either need the ati binary drivers - or the ones from the 
xlibmesa-dri package above.  I recommend the xlibmesa-dri ones, the work well 
for me.

Personally, I think that would be a mistake.
