That was fun! And we have a result:

I verified that the last good commit not only boots the BIOS but also boots the 
OS properly (and faster than 2.7.1).

  The command line was :

  qemu-system-sparc -nographic -bios ./openbios-sparc32 -M SS-20 -hda
  ./36G.disk -m 512 -cdrom Solaris_2.6_Software_05_98.img -boot d
  -serial telnet:0.0.0.0:3000,server -smp 2,cores=2 -monitor null

  It fails with a similar output when using bios ss20_v2.25_rom.
