For me Dominions3 runs with no problems on laptop with Gentoo, Intel GMA950 graphics, Xorg 7.2, Mesa 7.3 and xf86-video-intel 2.5.1-r1.

What do you mean exactly by "crashes"? In my experience most outright system freezes are driver related, with Intel audio drivers more likely a culprit... what is your audio setup? Try running dom3 with "-s -m" options to disable sound and music.
