First, I'd suggest changing the name of the init script from kvm to
kvmctl. On some platforms, installing the kvm package will include a
kvm init script which loads the modules.
I've also been working on an init script, based off some other efforts
that I've seen. It is written in python.
Ballooning is finally enabled in kvm-75. You will need a 2.6.27+ host

- requires 2.6.27+ host to work correctly
