sure. btw, I'm trying to track a problem I'm not sure is related to qxl
at all at this point:

 start a guest (no qxl). passes bios to guest fine (notice via change to
 display but also via kvm_stat)
 monitor: system_reset.
 doesn't pass bios. 900k/sec (or is that 2? the kvm_stat refresh time) exits

 with qemu-kvm rhel6 branch this doesn't happen.
 with qemu-1.0 (i.e. master branch) it does.
