Strange things:
- downgraded to 2.9 driver -> it still behaved as the 2.11 driver (=freeze after a while, can switch to console).
- back to vesa -> got an error about a KMS driver being loaded (!).
- fix for this was to purge the intel driver and reinstall it. This also restored the instant crash from times before. Looks, like I can dance between this and bug #565870 and we can forget the last comment (as that was no change but only the alltime state _with_ KMS).
Looking a bit deeper the 2.11-driver *required* KMS and enables this using a file in /etc/modprobe.d, which is kept after downgrade. That file needs to be killed to get at least vesa back.
