It is a Firefox issue on Linux (Ubuntu) only. Graphics handling on my Ubuntu 8.04 machine works great, a few examples:
1) Google Earth 4.2 render smoothly - even with sunsets over 3D-textured houses in Munich (Germany).
2) Opera renders the examples given above fluently.
3) Firefox running virtualized in Windows on VMWare on Ubuntu renders the demo-pages fluently.
4) Compiz effects - full bells'n'whistles - renders fluently.
To conclude: This issue can not be solved by adding a module section to xorg.conf. The culprit is Firefox on Linux (maybe just Ubuntu, cf. 1st comment in this issue).
