There are other Linux distros for the sparc platform but I would seriously take a look at NetBSD. Depending on what you plan to do with the system (you mentioned devel work) it is a better choice than OpenBSD.
I have no knowledge of any of the *BSD OS's. Would NetBSD or FreeBSD be a good choice for a home firewall or server? When answering, keep in mind that all I really know is Red Hat and Windows; everything else I ever used in the Unix world I've long since forgotten.
