Thank you all. I think I'll wait, however, do you think that that is the problem that cause

glxinfo | grep renderer
direct rendering: Yes
OpenGL renderer string: Software Rasterizer

On my ubuntu machine, I get :
direct rendering: Yes
OpenGL renderer string: Mesa DRI Intel(R) 965Q GEM 20090326 2009Q1 RC2 x86/MMX/SSE2

That diference definately explains poorer 3D performance in gentoo compared to ubuntu. IIRC GEM is a very new feature in the 2.6.29?? kernel, so at a minimum you'll need to enable it in your kernel, to be able to use that feature. There may be other things you need as well....

You'll probably want to run the very latest version of the intel driver, to try it, add the following to /etc/portage/package.keyword;
x11-drivers/xf86-video-intel ~x86
if you're running 32 bit or
x11-drivers/xf86-video-intel ~amd64
if you're running 64 bit, then emerge it again

Have you read http://en.gentoo-wiki.com/wiki/Intel_GMA? Should be better info in there
