It's great to know that SPARC is being used... not too long ago we discussed pulling the plug on SPARC support since we weren't aware of any users.
A big problem with maintaining SPARC is that the only full-system SPARC regression test we have uses a proprietary Solaris boot image that can't be distributed, meaning many people can't run the regression and can't debug problems when they occur. (That's why it took so long to fix the previous bug.) If you have the capability of building a simple freely distributable full-system boot test that we could integrate with our regressions, that would actually help a lot in terms of our ability to keep SPARC support from rotting away.
