Nope. Not ruling out a QEMU issue, but it's specific to sparc64 on Mac  
OS X host.
I never got further on sparc64, so the errors you are discussing now  
seemed like a leap forward. ;)

On Linux/amd64 I do get the OpenBIOS prompt with either 'open is not  
unique' or 'byte-load exception' (testing Solaris 10 U3, Solaris  
Nevada b127 and MilaX 0.3.2).

I'm at OpenBIOS trunk HEAD (r635) and was at QEMU master  
63e86b2e13396310feff1fe1a5988b5742487636.

With ppc or sparc32 emulation I do not have this issue. Debian/sparc32  
boots fine 'til login and Debian/ppc has some graphic glitches  
(penguin miscolored on OSX/Cocoa, missing on Linux/SDL) but gets to  
the first installation screen.
