I can toggle the button with the lid open and cat /etc/acpi/button/lid/LID/state and see it change between 'open' and 'closed'; and I know I could write myself a little script do something like calling radeontool to turn off the backlight, but I'd like to find a more official method.

The only thing I can find is a the standby/suspend/shutdown/logoff, system performance, and CPU throttling. I don't really want to do any of that - just put the monitor into stand-by, not necessarily the whole system.

In...
/etc/acpi/default.sh

there's a comment (with commented code you can use following it)...
# if your laptop doesnt turn on/off the display via hardware
# switch and instead just generates an acpi event, you can force
# X to turn off the display via dpms.  note you will have to run
# 'xhost +local:0' so root can access the X DISPLAY.

if radeontool or something will allow you to disable the display even
when you aren't in X, or without proper access to the display (like
xset requires) you might be able to even escape needing that xhost
setting. No way of testing it at all myself though.
