Bug#918966: new(?) backlight brightness script

Package: initscripts
Severity: wishlist
Version: 2.93-3

After upgrading and rebooting a virtual machine that has only a virtual 
serial console, I get this message:

/etc/init.d/brightness: 36: /etc/init.d/brightness: cannot create 
/sys/class/backlight/acpi_video0/brightness: Directory nonexistent

It's not critical, but I'm wondering if desktop features could be 
separated from this package. Or if there was a debconf knob to turn them 
all on and off easily?

Also, the error message could be avoided with some more checking:

if [ -d /sys/class/backlight/acpi_video0 ]; then
	readonly SYS_CONTROL=/sys/class/backlight/acpi_video0/brightness
	readonly SYS_MAXIMUM=/sys/class/backlight/acpi_video0/max_brightness
	readonly SYS_CONTROL=/dev/null
	readonly SYS_MAXIMUM=/dev/null

Best Regards,
