Increasing the DMESG buffer....

Dearest people,

I'm trying to get FreeBSD (back) into a couple orders of magnitude
more devices than you're thinking about.

When we talk about "the masses", let's keep in mind that we have
different ideas of what "the masses" are.

I'm trying to keep all of them in mind, rather than just the subset
that want to run FreeBSD on their desktop or high end servers.
