New Revision: 268772
URL: http://svnweb.freebsd.org/changeset/base/268772

Log:
  Allow efifb to be used with xf86-video-scfb. This is important for EFI
  systems without either a CSM or real graphics drivers, such as my Lenovo
  Haswell laptop.
  
  This provides working X with the small complication of a console cursor
  permanently overlaid on the upper-left corner of the screen that will be
  dealt with later.
  
  Also remove some redundant screen clearing.
