I reported earlier that after updating to current (turned out to 
actually be 3-stable, but irrelevant here), I had no response from the 
keyboard. In the meantime, I installed from scratch the current 
distribution on an nfs share, and had no problem. After tweaking the 
config a bit and moving the system to NFS, no keyboard again.

Turns out the problem was in my rc.conf. The line
wscons=yes
must be removed. Then the keyboard works as expected.

Now I have a new problem. Running X with fvwm2 window manager (as a 
non-root user), if I quit using the Quit in the fvwm menu, the server 
shuts down but again the keyboard doesn't respond. This worked with my 
previous setup, so I am not sure what changed.

If I kill -TERM the X server (as root), things shut down normally, and 
I get the keyboard back in console mode. Nothing I can do as a 
non-root user seems to get me back to console with working keyboard.

Hmmm, after a bit more experimentation, it seems the X server is 
trying to start back up, so it seems it is not getting completely 
killed by the fvwm. I'm wondering if it's a permission problem, since 
the server is running as route, but fvwm2 as a non-root user. Anyway, 
doesn't appear to be a keyboard issue after all.
