Since the ABI will not change anymore except in a backward compatible manner, the old concerns of matching userspace to kernel are gone. In terms of parity with the external kernel module, 2.6.23-rc1 will be very similar to kvm-29. -- Do not meddle in the internals of kernels, for they are subtle and quick to panic.
