intel_agp kernel module not found

I trying to use intel embedded HD 4400 graphics. As best as I know, it's need to load i915 kernel module (and the kernel module loader also try to load it) without success because it's depends from intel_agp module.

root@Laptop:/# lsmod | grep -i intel_
root@Laptop:/# modprobe intel_agp
root@Laptop:/# lsmod | grep -i intel_

When i try to load module, there is no error message, but the module is not loaded.

Than I searched for kernel module file:

find /lib/modules/3.2.0-4-amd64 | grep -i intel_agp
(no result)

But it's doesn't exists. How can I get this module?

In most of driver topic, there is an output of lsmod which indicate this module loaded.
