Intel gma945, mesa 7.5.1 slowish performance?

Question

im running kernel 2.6.31-rc9 for the record:
installing mesa 7.5.1 and all its deps for intel hardware drops from 800ish fps to about 400fps
downgrading to 7.5-2 and all packages linked to it fixes it.. anyone felt the hit?
packages which needed downgrading are
intel-dri 7.5.1-1 --> 7.5-2
mesa 7.5.1-1 --> 7.5-2
libgl 7.5.1-1 --> 7.5-2
xf86-video-intel 2.8.1-1 --> 2.7.99.902-1
any of these packages could be the culprit....

In my case (graphics hardware: Intel GMA X4500HD) it was not mesa, but the new intel driver that reduced performance drastically. Some time ago, I had put
IgnorePkg = xf86-video-intel
in my /etc/pacman.conf file to avoid the beta version of the intel driver. So I stayed with xf86-video-intel-2.7.1-1 for quite a long time. I did update mesa some days ago and the framerate in glxgears did not change, it stayed at 1200 FPS.
Today, I removed the IgnorePkg and updated xf86-video-intel to 2.8.1-1 and the glxgears framerate dropped to 500 FPS.
there was a performance hit when switching to UXA from EXA, this was fixed before, now, the new upgrade regressed this.
