OK.. Not sure what GTT is though :)

I've back ported the AGP driver (and vgapci) and I get..
vgapci0: <VGA-compatible display> port 0x1c60-0x1c67 mem 0xd2300000-0xd237ffff,0xc0000000-0xcfffffff,0xd2000000-0xd20fffff irq 16 at device 2.0 on pci0

(excuse the spam - I kept adding stuff to it trying to work out why it wasn't
doing anything then realised the new AGP needed vgapci)

With the ports xf86-video-intel I get..
(==) intel(0): Backing store disabled
(==) intel(0): Silken mouse enabled
(II) intel(0): Initializing HW Cursor
(II) intel(0): xf86BindGARTMemory: bind key 1 at 0x006ff000 (pgoffset 1791)
(WW) intel(0): xf86BindGARTMemory: binding of gart memory with key 1
        at offset 0x6ff000 failed (Invalid argument)

Fatal server error:
Couldn't bind memory for front buffer

I tried to build your git repo of the driver but I am getting..

I modified config.h to add those #defines and the man Makefile (configure is
fun!) and installed but now I get..

OK.
I really only want the 2D driver so DPMS works and the screen saver can
turn the monitor off (although faster 2D would be good as well)
