I see you have covered the usual bases with qemu. I can't suggest
anything else there.
It seems logical that qemu would need to run on top of X, in much the
same way that Firefox [just to pick an example at random] won't work
without X. I'm still a FreeBSD newbie though, so I have no idea how X
works. I'm still struggling to upgrade my Xorg to 7.2. [Stupid missing
OpenGL drivers! >:( ]
I would try installing X [good luck with that!] and see if that helps.
