I've never explored whether 3D acceleration works in any useful way, so I 
guess that the i810 driver works for me (at least with some monitors) by not 
using this support (or not depending on it)? It sounds unlikely that it works 
by sheer luck :)

In any case, not being able to support two monitors at least as well as it 
does with the i810 driver (whether it is with 3D acceleration or not) will be 
a clear regression. Not showing anything on the LFP too, btw ...
