It's really '-S' . I added this option to tell to qemu not to launch the
emulated code. This way, you have some time to grab the serial port
output and be able to edit the kernel's command line at startup (PREP
kernel allow this...). You just have to type 'c' in qemu monitor then
the kernel waits one second with the current command line displayed,
then boots if no chars were received.

It may not work: I didn't really test the network, just made sure that
the NE2000 was seen by the kernel. PPC system emulation is still very
experimental...

I never used this option, and it doesn't crash for me.
Could you try to launch it under gdb and send me a trace ?
