I just commited the first alpha release of the QEMU Accelerator Module (aka KQEMU) in the CVS. It gives better performance for the "x86 on x86" case by running most of the application code as is. It works only for a Linux x86 host running a 2.4 or 2.6 kernel. Linux 2.4 and 2.6 kernels and Windows 2000 have been runnning as guest OSes, but other OSes may work as well. As with every alpha kernel driver testing, it is better to backup your data before trying it.

KQEMU is _not_ open source as the rest of QEMU. It is a proprietary kernel module (read the LICENSE file) and will stay so until a gentle company decides to subsidy the QEMU project.

KQEMU usage is optional: you can disable it at compilation or run time, so no one is forced to use it.
