Actually, it looks to me like after this line runs:
OF_interpret("stdout @ is my-self "
"addr char-height addr char-width "
"addr window-top addr window-left",
4, &windowleft, &windowtop, &romwidth, &romheight);
windowleft and windowtop contain legit addresses, but romwidth and
romheight have garbage in them. It might be possible to chalk this up
to bogus QEMU firmware, in which case, whatever.
