Running our standard ARM board tests is a case of:

git clone http://git.yoctoproject.org/git/poky
cd poky
source oe-init-build-env
echo 'INHERIT += "testimage"' >> ./conf/local.conf
MACHINE=qemuarm bitbake core-image-sato
MACHINE=qemuarm bitbake core-image-sato -c testimage

You could replace core-image-sato -> core-image-minimal for a smaller
image and fewer tests or try core-image-sato-sdk or core-image-lsb-sdk
for more.

The Quick Start guide is at
http://www.yoctoproject.org/docs/1.8/yocto-project-qs/yocto-project-qs.html and 
has various things like precanned lists of prerequisites for the package 
manager.

Not sure which other boards you could try booting but I know the Zaurus
machines did work a long time ago as we submitted the qemu code. They
are now in their own layer and I've not tried them in a long time.

The above will build its own qemu-native as there are some patches we
rely on (like the network fixes). You can point the qemu recipe at
different source easily enough.

Cheers,
