Dear List,
I've stumbled upon a possible misbehaviour.
I've run df_dok with and without the i830 being used. Here are my results:

they're almost identical!
there was a previous mail on this ML, saying that i830 lacks the most
important
features of i810, like blit acceleration, and such...
so whats up now with i810/830?
this way directfb is unusable on many embedded platforms, as those has
i852/855...
Thanks,
