Attached is a not-very-pretty patch to qemu-0.8.2 that allows it to use kvm.

You will need:
 - libkvm.a from the userspace posted previously
 - qemu 0.8.2 plus this patch
 - some twiddling with the configure_kvm() function in ./configure to 
set paths
 - run ./configure with --enable-kvm
 - a machine with VT, enabled in the BIOS if possible, running a kernel 
with the kvm patches applied and configured
 - modprobe kvm
 - access to /dev/kvm

Runtime is exactly the same as qemu.  You will need the same BIOS 
shipped with qemu.

Some notes:
 - the display is optimized by tracking which framebuffer pages have 
been dirtied since the last refresh and updating only the affected scanlines
 - the display bits are derived from a similar Xen patch
 - I've only tested this with SDL, not VNC
 - keep your original qemu binary since this one can't run without kvm
