No, for various reasons, including:

- there's no good way to key packages as 'install this if you
  have hardware 3d support'
- the 2d screensavers can (and do) chew just as much CPU as the 3d

Patches that allow switching automatically to the blank screensaver
in the case of running on battery, etc. would certainly be considered;
you'd probably want to hook into the dbus event framework for getting
power events from the kernel in the future.
