11MPCore isn't in the set of models I usually run. However
"just sits there" is often a kernel configuration bug
rather than a QEMU bug.

(1) Does your kernel boot on the real hardware?
(2) If you add "earlyprintk" to your -append string
(and ensure early printk is selected as a config option
when your kernel was built) do you get any kernel output?
