thinkpad-acpi/ibm-acpi is *out of the circuit* for brightness control on
GPU-based brightness setups on modern X.org.  That means your T61.

If you want to try the former methods of backlight control using
thinkpad-acpi, be my guest :-)  Read the docs on
Documentation/laptops/thinkpad-acpi.txt and use the brightness_* parameters.
Make sure ACPI video is not loaded, though.
