Thanks for your work! What is the estimated time when it will go HEAD?
May I expect that my powerbook4,1 machine will get ability to sleep under the FreeBSD now?

I understand that you provided these so people with another archs could test whether it doesn't break anything, but what about actual PPC users? ;)
Considering that powerpc is a Tier 2 these days, it's not that easy even to get svn quickly for it to grab your tree, so I would ask adding projects_pmac_pmu to the powerpc building. Thanks.
