That is my experience.

bitbake xf86-video-fbdev

Correct, include xf86-video-fbdev in the image recipe.

I don't think bootargs needs to change.

lastly, modify /etc/X11/xorg.conf to include:

Section "Device"
        Identifier      "fbdev driver"
        Driver          "fbdev"
        Option          "fbdev"         "/dev/fb0"
        Option          "Rotate"        "CCW"
EndSection

Thanks,
Cliff
