If you are running Nemo from ubiboot, here is a nice hack needed to fix the framebuffer problem in the kernel...

Background:
When you use Wayland instead of X11, the default framebuffer configuration of N9 is not correct. (that's 3 framebuffers, each sized 2MB)
Instead you would need to have one larger FB with 6MB of memory allocated to it.
The solution to this is to add kernel command line parameters "vram=6m omapfb.vram=0:6M", but the current implementation of ubiboot has automatically parsed command line with no option to add your own parameters to it.

Solution:
You can get around this by injecting the needed parameters as sedscript arguments to the command line mangler.
In ubiboot.conf there's the following line: G_NEMO_INITSCRIPT="\/sbin\/init"
You need to change that to G_NEMO_INITSCRIPT="\/sbin\/init\ vram\=6m\ omapfb.vram\=0\:6M"

In the next ubiboot release there will be a feature for appending your own command line arguments, but meanwhile you can use this hack to experiment with Wayland
