Gentoo + KDE4.4 + compiz-fusion + 1300 FPS

Yes, maybe 1300 fps it is not exciting for someone who has ATI or NVidia card on board, but for my Intel 945GEM it’s back to times before KMS.
Anyway few months I suffered from 3D performance regression. I was happy if I saw 300 FPS. Now desktop can look great and to be fast. How to do it under Gentoo:
1. your system should be ready for “unstable” packages. Hence please accept ~x86 keyword in /etc/make.conf
ACCEPT_KEYWORDS="~x86"
