The fact that /dev/sndstat exists means that there is a sound driver
that works. From the contents you can see that it is indeed the snd_hda
driver ("HDA Realtek ALC885 "). You can also see that there are four
sound outputs. Currently the digital HDMI is the default.
You can configure the sound hardware through sysctls. If you run "sysctl
hw.snd" you'll see a list of things you can change. With 'sysctl -d' you
can see what a particular sysctl does. In this case one that is
interesting is 'hw.snd.default_unit'. The different outputs in
/dev/sndstat will be connected to different sockets on the machine
(e.g. front/back panel). Try setting hw.snd.default_unit to 1, 2 or 3
and see if that helps.
It could be that you have to unload and reload the snd_hda module after
setting the default channel. You might also have to restart the volume
control applet.

Ok. I think it should be a bug that the mouse isn't properly detected
when connected at boot, but since the USB stack has been replaced in
8-CURRENT, I don't know if anyone is willing to go bughunting in the 7.x
USB stack.

That is not abnormal. A lot of mice need special zaxis mappings.

Then use an xterm instead of a gnome-terminal. Acroread depends on Linux
emulation. Maybe you're missing some bits there?

I've never used pulseaudio. I prefer esound.

This looks pretty harmless.

Look at kvm_getenvv(3), in the BUGS section:
"In order for kvm_getenvv(3) to function correctly, procfs(5) must be
mounted on /proc"

Looks OK.
