Related to what you mentioned, I found another wsconsctl setting, display.backlight. It apparently accepts a value from 0 to 100 with a value of 0 to 99 treated as 0. Setting it to 0 causes the same effect I have been getting with the screen blanker in wscons and X. Setting it to 100 puts it back to normal.
I currently have the brightness turned down to 0, and using the "X symbol" built-in screen saver. It'll do for now. I'll look for any possible firmware updates, but I don't believe there have been any for several years.
