backlight

I'm using an IBM Thinkpad X21 as a 3G router. It's running a server install of lucid. The laptop has the lid up most of the time. There is no X, just a plain console. The colsole blanks itself, but the LCD backlight is always on.

The graphics chip is ATI Technologies Inc Rage Mobility P/M AGP 2x (rev 64).

The following modules related to the framebuffer are now loaded:

$ lsmod | grep fb
fbcon                  35102  71 
tileblit                2031  1 fbcon
font                    7557  1 fbcon
bitblit                 4707  1 fbcon
vga16fb                11385  1 
vgastate                8961  1 vga16fb

Can I make the LCD backlight turn off when the colsole is unused and have it turn on automatically when needed?
