Yeah; a keyboard command error and a single letter "s" with -nographic:
qemu: unsupported keyboard cmd=0x57
The segmentation fault is actually the Qemu host process dying. The VNC
display looks more interesting; it seems that something is writing all
over the screen memory just before the crash happens.
I believe from Nick's email that he can also recreate this using latest
OpenBIOS SVN, a recent pull of Qemu and a Milax 0.3.2 ISO image.
