If somebody else's kernel boots but yours does not then the chances
are very high that there is a problem with your kernel (probably
a wrong config) which you'll need to debug the same way you'd
debug this kind of misconfiguration on real hardware. Connecting
an ARM gdb up to qemu and singlestepping kernel startup may be
helpful.

If there's no output of the "Uncompressing the kernel" message
this is almost certainly a kernel configuration or compilation
problem -- QEMU's serial port code is pretty heavily tested.

(Why are you using the 11MPCore model anyway, just out of interest?)
