We recently upgraded our Sparc64 Gentoo box. When we rebooted we got an error at the console when trying to boot that just said Sprogram terminated. It turns out that this was caused by an error with the SILO boot records. See this article for more information on installing SILO.
To get our system to boot correctly again, we simply booted our root partition with install-sparc64-minimal-2005.1.iso available here and re-ran silo:
# silo
/etc/silo.conf appears to be valid
# ls -l /boot
total 4052

You can see that the second.b record was changed when we re-ran SILO. Also, you can see that the upgrade yesterday did touch some of the other boot records. We have never seen Gentoo mess with these records on our other boxes, but we usually run a custom kernel and don't let Gentoo emerge those. Anyway, do be aware of this behavior.
