Strange. Can you also post a few lines of 'vmstat 1'?
Maybe we'll see a lot of context switches in there.
Not that many. Still running the same w7 guest, still
~25..27% CPU usage reported by top for the kvm process,
here's `vmstat 5' after a while (I tend to use larger
delay to mitigate large(ish) spikes):

Stumped.
A shot in the dark: can you try running with vnc instead of sdl (and
disconnecting your vnc client while measuring)? Maybe the guest is
doing a lot of vga updates.
