This doesn't work with Roberts runqemu conversion to python.

I did try adding http://git.yoctoproject.org/cgit.cgi/poky/commit/?h=ma
ster-next&id=e91d7bf00bfab5142bc290425103971b897c208b however this
requires the use of the dtb file and doesn't work with older kernels.
I'll see if I can come up with something better based on kernel
PREFERRED_VERSION...

Cheers,
