Looks like the last stage of the kernel loader wasn't able to determine the
CPU model? Or at least didn't like it. Maybe the OpenSolaris version
you are booting doesn't support the specified (or default) cpu model?

And... Solaris 2.5.1 on sparc32 also looks pretty similar with r733:

Jumping to entry point 00004000 for type 00000005...
null path
krtld: error during initial load/link phase
Unhandled Exception 0x00000007
PC = 0x0010724c NPC = 0x00107250
Stopping execution

Unmodified Solaris 2.6 doesn't get this far, I guess due to the 80
chars limitation. Will check the patched version later.

But all in all it looks like the problem is buried in OpenBIOS, since
qemu is definitely good enough to boot 2.5.1 under sparc32.
