This change is not agreed too yet. Antonio and I are proposing a
different solution.
http://comments.gmane.org/gmane.linux.fbdev.devel/7118

The alternate solution takes into account that fbconsole is the only
user of softcursor and moves softcursor into console.  fbdev drivers
then only expose a cursor entry point if they have a hardware cursor.
If they don't the entry point is NULL.

Nether solution should break existing apps since the existing
softcursor scheme was broken from user space and unusable.
