[edit] Kernel Configuration

Enable the chipset driver under /dev/agpgart, then enable the Direct Rendering Manager appropriate to your card.
If you would like the i915 driver to be built into your kernel (instead of being loaded as a module), check for the ACPI Button and Video choices to be set to built-in: The entry for "i915 driver" will disappear from the menu if the ACPI items are set to "module"!

Linux Kernel Configuration: Enabling Intel KMS

Power management and ACPI options ---> [*] ACPI (Advanced Configuration and Power Interface) Support ---> -*- Button -*- Video Device Drivers ---> Graphics support ---> <*> /dev/agpgart (AGP Support) <*> Intel 440LX/BX/GX, I8xx and E7x05 chipset support <*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) ---> <*> Intel I810 <*> Intel 830M, 845G, 852GM, 855GM, 865G (i915 driver) ---> <*> i830 driver <*> i915 driver [*] Enable modesetting on intel by default

[edit] USE Flags

Set the following in make.conf.
Then re-build the X drivers;

[edit] User Configuration

For Hardware Acceleration and DRI access you need to add the user to the video group. It should work by default.

[edit] X11 Configuration

If you find yourself needing to tell X11 to use the intel driver, set Driver to "intel" in /etc/X11/xorg.conf as in the example below,
For further options see the intel man pages,
