I have been running 9.99.17 on RPi3+ and did ./build.sh current, which
produced 9.99.69 -- and it works perfectly, no garbling.  I just copied
src/sys/arch/evbarm/compile/obj/GENERIC/netbsd.img to /boot/KERNEL7.IMG and
rebooted.

# sysctl -a|grep freq
machdep.cpu.frequency.target = 1400
machdep.cpu.frequency.current = 1400
machdep.cpu.frequency.min = 600
machdep.cpu.frequency.max = 1400
machdep.cpu.frequency.available = 600 1400

So I'm now more confused than ever.
