It works great for me.  The only thing I would like better is if the target
were added to the end of the customconfig file, so that you wouldn't
accidentally pick up the wrong config.  (i.e., customconfig-qemu or
customconfig-s2891).

I think that could be considered a matter of taste.  Maybe we should add the
custom-config option for the kernel as well.

Thanks,
Myles
