You need agpgart and also a specific agp-driver for your motherboard (since you have a via chipset I guess you should select "VIA chipset support") but you don't need to have them compiled into the kernel, you can have them as modules.
You also need to load the correct drivers for X in /etc/X11/xorg.conf (probably):
Load "radeon"
Load "dri"
I'm sure there are a lot of other things needed as well.
To check if you have DRI working, type 'glxinfo' in an xterm.
If it says "direct rendering: Yes" it's working. |

I've got a similar config. Here are my kernel settings:
| Code: | Device Drivers -->
Character Devices -->
/dev/agpgart (AGP Support) -->
M ATI chipset support
M VIA chipset support
Direct Rendering Manager -->
M ATI Radeon |
Next, /etc/modules.autoload.d/kernel-2.6 should contain something like:
| Code: | agpgart
via-agp
radeon |
Then make sure your /etc/X11/xorg.conf (or XF86Config) is set with the following:
Add this to section "Module"
| Code: | # This loads the GLX module
Load "glx"
# This loads the DRI module
Load "dri" |
In my case, the "Device" section is set up as follows:
| Code: |
Section "Device"
Identifier "Card0"
Driver "radeon"
Option "AGPMode" "4"
EndSection |
Note that even though I've got an 8X AGP slot and card I have to run at "4".
Add this to the end of the file:
| Code: | Section "DRI"
Mode 0666
EndSection |
With this setup my glxgears shows an average of 2250fps (at 16 color depth). Obviously, your mileage will vary based on your hardware. |
