Hi Simon,
Thanks to your hint I got it working after all, here is the story:
1. glxinfo said that there was no framebuffer bound to several terminals. I googled it up and found out that my laptop has apparently two graphics chips: an i915 and an nvidia chip. The idea is to use the intel chip for normal work and the nvidia chip for heavy 3D operations.
2. the entire linux desktop would freeze sporadically with either the proprietary nvidia driver installed or the open source nouveau driver installed.
3. I removed every nvidia driver and installed bumblebee
4. speeddreams would launch now but parts of the 3D graphics were blank. Disabling texture compression worked and the game runs with 60fps at full resolution.
