[arch-general] thinkpad t61 and not able to adjust brightness

[Adam Stokes]

So pressing the fn home/end for brightness alters :

/proc/acpi/video/VID/LCD0/brightness

doing an:

echo '100' >/proc/acpi/video/VID/LCD0/brightness

My .config for the kernel is set to:

CONFIG_THINKPAD_ACPI_VIDEO=y
CONFIG_VIDEO_OUTPUT_CONTROL=m
CONFIG_ACPI_VIDEO=m

lsmod shows:

thinkpad_acpi          70316  0
rfkill                 11444  4 iwl3945,thinkpad_acpi
led_class               4344  3 iwl3945,sdhci,thinkpad_acpi
nvram                   7868  1 thinkpad_acpi

dmesg shows:
thinkpad_acpi: ThinkPad ACPI Extras v0.22
thinkpad_acpi: http://ibm-acpi.sf.net/
thinkpad_acpi: ThinkPad BIOS 7LETA7WW (2.07 ), EC 7KHT24WW-1.08
thinkpad_acpi: Lenovo ThinkPad T61, model 6464Y1E
thinkpad_acpi: ACPI backlight control delay disabled
thinkpad_acpi: radio switch found; radios are enabled
thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness
control, supported by the ACPI video driver
thinkpad_acpi: Disabling thinkpad-acpi brightness events by default...
thinkpad_acpi: Standard ACPI backlight interface available, not
loading native one.

kernel is 2.6.29-ARCH

anyone know why the brightness still refuses to work?
