Do i need agpgart

Every time my system boots i get a message about agpgart module not being loaded or something like that. I had a look around this forum to understand what i have to do, but in the end got more confused. So in the end i commented agpgart in rc.module so that it doesn't load anymore, but my question are:

What is the purpose of agpgart? i know it has to do with AGP and video cards but what does it do?

Do i really need it for my system althouth i have an AGP 8X and a video card?

If yes, what do i need to do for agpgart module to be loaded? Any configurations or drivers to be installed?

i'm not sure entirely what it does, but without it you won't be able to use your video card to it's full potential. you should be able to run the standard VESA drivers no problem, but if you have a 3D graphics card or whatever, you'll be wasting it. if you don't play a lot of games, or set your resolution higher than 1280x1024, then it probably won't make much difference.

With no details about your hardware config, it is a difficult question to be answered.
Basically agpgart module/driver manages the agp bus of your video card.
Agpgart can be included into the kernel or compiled as module. (nothing strange 'til now).
Many video cards and related drivers (ie nvidia) have their own agp internal module but if available their primary choice is to load the agp kernel module, leaving the built in module as a secondary choice.
They also prefer the agp kernel module to be loaded by the X server, instead having the module loaded at boot time.
If the agp kernel module doesn't work properly, you are allowed to specify what agp module you want the X server to load by editing your XF86Config file.
ATI cards/drivers work slighly different, and you should compile into the kernel the dedicated ati agp and dri modules as well for the ATI cards supporting 3D acceleration , but to be honest I do not have much experience with ATI cards, so I cannot give details on that.
