This is not a problem with the display driver.
 
Version 2.6 kernels require a second kernel module in addition to agpgart, which should be named similar to the manufacturer of your motherboard AGP chipset. This error message should occur if the other agp module is not loaded.
 
This issue can be worked around as follows:
 
   1. First make sure that agpgart is loading properly.
 
   2. To find out which AGP controller your motherboard uses, issue the following command: lspci | grep AGP
 
   3. To find a list of AGP related kernel modules installed on your machine, issue the following command and look for a module (*.ko file) that suits your AGP Controller: ls /lib/modules/`uname -r`/kernel/drivers/char/agp
 
   4. Use the modprobe command (as root) to load the module. For example: On a motherboard using a VIA® AGP Controller, you would load the via-agp.ko using modprobe as follows (notice that the trailing .ko is omitted): modprobe via-agp
 
Check the modprobe manpage for more information on loading kernel modules.
 
   5. To verify that the AGP module is already loaded, run lsmod as root. With the XServer running and the connection established, the usage count of this module must be greater than zero.
