You're welcome to test it, it is under
git://kvm.qumranet.com/home/dor/src/linux-2.6
Checkout the build-trunk branch.

I don't have the time to merge it currently. Note that there are also
some more balloon drivers for other architecture (s390).

The Linux guest driver change the balloon size using a simple char
device.
In our windows drivers we control the balloon from the host using pci
device. Qemu handle/controls the balloon hypercalls for mgmt reasons.
