Booting Solaris 10 or 11 for Sparc in qemu-system-sparc64

Have been searching for this myself a while ago but unfortunately I did not succeed in starting Solaris 10 (or 11) using QEMU with sparc64. I stopped trying after I read the page http://wiki.qemu.org/download/qemu-doc.html#QEMU-System-emulator-for-non-PC-targets section 4.3 which states that the emulator is not usable but may boot some kernels.

Qemu-system-sparc64 will boot and run successfully only old versions of Solaris(7< 7 not included) and with custom bios(taken from old Sparc workstations). Of course you can try maybe with next releases versions like Solaris 8 or 9 Remind that the kvm module is only for x86 architecture,so Sparc emulation will be really slow. This is a good how-to to see.
