vbetool post did turn off the backlight and it came back on when run
from a prompt. But, following a lid event the same command did not
turn the backlight back on.
Also, turning off X, and creating a lid event while on a text console
produces the same results.
I believe I remember a binary driver for the graphics being among the

that will help.
