Intel XOrg optimum performance - how to?

[colo]

Hello forums,

I'm running an Intel DG965WH (Intel GMA X3000/G965 onboard) on Gentoo ~amd64, with the latest releases of xorg-video-intel (2.4.2), xorg-server (1.5.0), and mesa (7.1). My desktop is KDE 3.5-based; my preferred video acceleration architecture is EXA. Relevant xorg.conf parts below:

Section "Screen"
        Identifier    "SCREEN0"
        Device        "G965"
        Monitor       "E2200WS"
        DefaultDepth  24
        Option        "Accel" "true"
        Option        "AccelMethod" "EXA"
Subsection "Display"
        Depth         24
        Modes         "1680x1050"
        ViewPort      0 0
EndSubsection
EndSection

Section "Device"
        Identifier    "G965" # intel gma x3000
        Driver        "intel"
        Option        "DRI" "true"
EndSection

I'm wondering if there are any options I missed out so far, and if there's a way to squeeze out that little bit of extra-fluidity of my setup. Any pointers?

Tia,
