I've got an Ultra 5 running -current here that I could give you access to,
if it'd help. I have tons of free time, so if you're willing, I could try to
work on some of your sparc64 TODO list. I'm new at NetBSD kernel hacking,
and have been needing a good reason to get into it for a while. Maybe this
could give me a good start.

I don't use ACPI even though my motherboard supports APM or ACPI; But if I
were to give one opinion on ACPI: it needs to be made a lot less spammy.
Every ACPI-enabled dmesg I've ever seen posted has almost as many
'PNP<whatever> not configured' messages as it does normal boot messages.
