Haven't had time to play, but I was thinking about this when bisecting
an i915 bug last week. In that case none of the kernels failed to boot,
they just had busted modelines. Do you have support in this tool for
testing some condition on the system after it boots? I would guess I
probably would have needed something more heavyweight (that could run a
script to look for busted modes on the target after booting).
