A short update: I've tried with Ubuntu and I can run dom3 without problems.

Then I decided to try ramarren's configuration and IT WORKS! thank you ramarren.

So the problem was due to the use of relatively old drivers versions. I have to say that lately gentoo has been VERY slow in updating packages. I think the stable branch is behind ubuntu!

Ramarren can you please share also you xorg.conf file? A new version of the intel driver requires new options and I would like to try yours.
