Following up on my own post in case anyone else is digging into this...
It's apparently possible to use "xscreensaver-command -watch" and grep, then set /sys/class/backlight/rpi-backlight/bl_power based on BLANK or UNBLANK messages.
So far I have a script that will respond to messages by just printing "Blank" or "Unblank" to the console. The best solution would be an xscreensaver "hack" that can be picked from the GUI. I'm still digging through the docs to find whether that's doable.
