Different chipset, but...
The 2.6.29.3 and 2.6.30-rc2 kernels give the best performance for me (not much different between the two). Kernel 2.6.30-rc3 and beyond all exhibit performance regressions for my 855GM chipset. The latest xorg-edgers drivers also slowed things down slightly.
Bleeding-Edge users,
I've updated the guide to fetch the -rc6 kernel, if you're interested.
rc6 gives me the same performance regression as rc3-4-5 :( does anyone know why?
rc6 fixes the problems I was having with bluetooth (kernel panics) so it is great for my aspire one. I rebuilt it with a small variation from kuki linux's kernel configuration, and now my A1 boots in less than 20 seconds, suspends with /home on a sd card without problems, and has finally half-decent video performance. And with last night's xorg-edgers drivers, UXA performance in glblur is up to 24fps, nearly on par to the max I had in intrepid with EXA (30fps). Google Earth is almost usable under kde4 with compositing on, the screen corruption is gone, it is just very slow updating the globe.

unfortunately it is not that simple: i'm having good performance with rc2 and safe intel drivers (not xedgers ones); any other kernel i've tried gives me the same, poor, performance (even 2.6.29); it seems for me that the improvements cited in phoronix about 2.6.30 are gone with rc's later than rc2 :(
Have you tried to disable tiling? Although tiling is supposed to give a considerable performance boost, it's currently buggy on my chipset and actually halves 3D performance (e.g. ppracer gives 15fps when tiling is enabled, vs 30fps with tiling disabled).
Conversely, if you already have tiling disabled, enabling it may provide a performance boost for your particular chipset.
it's the same, with or without tiling enabled :( by the way, i own a GM965/GL960
