Chris,

Don't you find bzImage under your work directory 
(<machine>/tmp/work/<machine>-poky-linux/linux-yocto....) ?

I just gave your steps a spin with the beta release, and I do see that 
the image is missing in my deploy/images directory, but I do find it in 
my work directory.

I'm just pointing this out in case you're stuck wanting a new image to 
work with.
