Hmm, can't see them in this list http://www.sun.com/bigadmin/hcl/data/os/systems/views/sun_systems_all_results.page1.html but best you can do is download installation CD and try to boot it. Or maybe you will be able to use http://www.sun.com/bigadmin/hcl/hcts/device_detect.jsp
Anyway all your HW is supported here http://www.openbsd.org/sparc64.html (in case you will not be able to use something from Sun) -- This message posted from opensolaris.org
