Why do you think that it is not-a-bug even if it stopped working? I don't
think it is a feature as acpi video driver should control backlight levels on
laptop that provides generic ACPI based backlight support which is the case of
ThinkPad T61. Or at least it used to be with up to 2.6.24 kernels.

I can read sane values from /sys/class/backlight/acpi_video0/* but changing them
has no effect on the backlight.
