The _first_ time I press Fn-LCmd, it (powerd?) reports power button
pressed and starts an orderly shutdown.  It gets around to unmounting
filesystems, but since I'm currently operating it netboot/NFS-root, it
never finishes shutting down and just hangs (if I had DEBUG defined, it
would print an endless procession of "nfs_timer: error 49 ignored"
messages and never actually finish powering off).

At this point, there is no powerd running anymore, so the _second_ time
I press Fn-LCmd, it produces the kernel message and shuts down immediately.

I suspected this would be the answer.  Oh well.  [ rambling deleted ]

I noticed that its default mapping is as the right-Alt key.

Also, Shift-Fn-{Up,Down}Arrow does scroll terminal windows, but its very
sensitive to order.  You MUST press Shift well before pressing Fn.  I'd
gotten used to (in MacOS X) just mashing LShift-Fn simultaneously and
pressing the desired arrow key.

Mouse operation deteriorates over time.  After a few hours, the mouse
will lose a coordinate, or be limited to a small region of the upper
left portion of the screen, and eventually, be stuck in the upper left
corner of the screen.  I was using the trackpad exclusively at the time,
but plugging in a USB mouse after the fact didn't change the behavior.

Any mouse event (motion or button) will send the mouse to the upper
right corner of the screen.  In a multi-pane graphical environment (fvwm
in my case) this will warp the screen to the upper-right workspace from
any other place.  In fvwm, you can use Alt-Tab to bring up a window list
and warp to any window on any workspace of the current desktop, so you
can navigate a bit while the mouse is stuck.
