I believe the main problem would be the graphics driver -

I was thinking of creating a meta-intel/staging area for

I also see that ASRock are now making a board

OK, good to know. The only Cedar Trail hardware I have
access to is the
Acer Aspire One I have here - let me see if I can get
something going on
My first attempt to build cedartrail-nopvr finds that meta-intel has an
unmatched mesa_9.1.3.bbappend, but I suppose I can configure it to ignore
that since I'm not building graphics. However, meta-cedartrail contains an
unmatched linux-yocto_3.0.bbappend and linux-yocto-rt_3.0.bbappend. I don't
know how to fix that.
You should just be able to delete those 3.0 .bbappends - they're of no
use at this point.

I actually used yocto-bsp to create a brand new cedartrail BSP, called
meta-cdt, with just a vesa graphics machine called 'cdt-vesa':

It built fine here, but it wouldn't boot on my Aspire One, but I
couldn't boot either of the official 'danny' cedartrail (cedartrail and
cedartrail-nopvr) images I built either.

I'd be curious if the meta-cdt layer would work for you, though.
