Yes, pixel-based drawing is still the default.  It's only for drivers
(matrox and sbus) where it might be needed.

If you mean one card with multiple heads, that will need driver-specific
support.

Because of the massive rewrite, there wasn't really enough time to add
major feature sets to the framework.  Most of the effort was spent on
bug fixing, cleaning up, and speeding up the code (to justify the
rewrite). 

It does have one benefit though, the newer code should make it easier to
add an infrastructure on top of fbdev, such as xinerama-style support. 
But this will be in the future.

Yes, to give people time to port their drivers.
