 FWIW: it works fine on real hardware (with OpenFirmware).
 
 Mark, could you have a look and tell us what firmware call goes wrong and
 what its args are?
 
 Should be enough to boot the sparc64 HEAD iso image (from 
 http://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/latest/images/NetBSD-9.99.18-sparc64.iso)
 in qemu.
 
 Thanks!
