Slow glxgears with Intel 945GME

My overall X performance seems to be a bit slow and laggy on my eeePC 1000H with its integrated Intel 945GME. glxgears shows a value around 60 fps (maybe limited by vsync, but I don't know how to disable it to check if this is the problem). I'm using the xf86-video-intel driver from the testing repository and the following xorg.conf settings

Section "Device"
    Identifier  "Card0"
    Driver      "intel"
    VendorName  "Intel Corporation"
    BoardName   "Mobile 945GME Express Integrated Graphics Controller"
    Option        "PageFlip" "true"
    Option        "TrippleBuffer" "true"
    Option        "AccelMethod" "EXA"
EndSection

Section "DRI"
    Mode         0666
EndSection

And I get the following warnings in my Xorg.log

(WW) intel(0): Bad V_BIOS checksum
(WW) intel(0): Register 0x61200 (PP_STATUS) changed from 0xc0000008 to 0xd000000a

(WW) intel(0): PIPEASTAT after: status:
(WW) intel(0): DRM version 1.9 or newer required for Page flipping. Disabling.
(WW) intel(0): Option "TrippleBuffer" is not used

Anyone got an idea how to improve the situation?

TrippleBuffer is wrong spell, it should be TripleBuffer.

BTW, TripleBuffer did slow down your 3D performance, so don't enable it.

PageFlip require DRM 1.9 which I don't have on my Ubuntu. So, I can't test it for you.
