This is the second part of "broken cfb* support in the 2.5.31-bk".  I
needed fbcon-cfb2 on one of my systems, and so I went through all
fbcon-* drivers and fixed them.

line_length, type, type_aux and visual were moved from display to
fb_info in last James Simmon's fbdev update.  Unfortunately lowlevel
support modules were not updated.
