Are you kidding? first off MIPS is only as open as x86 in the IP sense that the ISA is open you have to design your own implementation and even then license it assuming you can afford it. There is no license currently required for SPARC and when there was I understand it was rather cheap (or so gaisler research says developer of the LEON Sparc)
There are full design specs and even HDL models (LEON and OpenSparc namely) available for sparc where is the model for the loonsoon (other MIPS models don't count since the implementation will be different)? I sure can't find any models for the CPU and all indications point to it being a proprietary implementation.
MIPS and SPARC are very similar from what I have read of the specs and taking a MIPS/DLX centric cpu organization class they are both RISC after all.

OpenSparc would seem to be more FREE (if you consider GPL free) than this.
