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':

http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-contrib/log/?h=tzanussi/meta-cdt-v0

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.
