Is there a specific version of OBP that you're aware of that works?
That'd sure be nice.

Title:
  qemu-system-sparc  in qemu 1.7.0 fails to boot with Sun ROM

Status in QEMU:
  New

Bug description:
  
  1.7.0 seems to have broken booting on SPARC ... at least with a Sun ROM.  
Everything fails with "data access exception."  1.6.{1,2} qemu-system-sparc 
binaries both boot the same images that 1.7.0 fails to boot.

  Type  help  for more information
  ok boot disk1
  Boot device: 
/iommu/sbus/address@hidden,8400000/address@hidden,8800000/address@hidden,0  
File and args: 
  Data Access Exception

  Starting with following command:

  sudo qemu-system-sparc -m 256 -M SS-5 -nographic -bios 
/home/img/ROMs/sun/ss5-170.bin \
