[MinnowBoard] Kernel .config file lacks CONFIG_FB_DEFERRED_IO

I am trying to build a frame buffer driver. When I build the driver against
Ångström kernel  header sources, I am getting this error:

* error: 'struct fb_info' has no member named 'fbdefio'*

After researching the problem, it seems caused for the lack of a setting in
the kernel .config file:


(after fb.h, if CONFIG_FB_DEFERRED_IO is not defined, fbdefio is not
included in struct fb_info)

I tryed just to add the line to the file but it still does not work. For the
record my Ubuntu system does include CONFIG_FB_DEFERRED_IO setting.

I hope that some one could provide some guidance in this regards.
