Thank you for the reply, Allan.
I bumped kern.msgbufsize quite a bit within loader.conf. That's how I
discovered that that tunable worked. But then needed to eek it down,
until I found the actual top of the output -- had to bounce the box
quite a few times. :P

ODD. Because running RELENG_8, or 11-CURRENT on the same hardware, and yes,
with BOOT_VERBOSE && VERBOSE_LOADING. I received the entire buffer.

Thanks again, Allan.
