These images are for the "versatilepb" machine emulated by mainline Qemu
(note "-M versatilepb" in the .sh file) and they predate the Neo1973
emulator release - whose point is running the native images from

VersatilePB machines don't have any audio hardware, so try emulating a
Neo1973, possibly using the openmoko/flash.sh script. The audio emulation
is not heavily tested and the sound quality will likely be poor - I
recommend the Xoo or Xephyr approach for any serious audio related task.
If you'll be using qemu and have problems getting it to output sound,
you can set the QEMU_AUDIO_DRV variable to tell it what output driver to
use. Valid values are:
oss, alsa, sdl, none, wav, fmod
I had most luck with oss.
