Now that the cdev_fb_init() macro demands a "poll" function,
all frame-buffer (FB) drivers need that defined somehow.
In the, sparc port, wrappers were added to each FB driver.

I prefer to fix the problem in conf.c rather than adding a
do-nothing wrapper to every frame-buffer driver.

Just wanted to share the idea...
