how do I switch to xbacklight kernel-mode?

I dont agree with you, I have a nvidia gpu in my r61 and it works just fine. I 
can change brightness by pressing the FN+Home/End keys on the keyboard or by 
echoing values in the acpi-sysfs file.

I am using the latest BIOS (2.10/1.08), kernel 2.6.24.2 with the latest 
thinkpad-acpi 0.19 snapshot and these kernel 
parameters: "thinkpad-acpi.experimental=1 thinkpad-acpi.fan_control=1 
thinkpad-acpi.hotkey_report_mode=2"

my thinkpad-acpi kconfig: 
CONFIG_THINKPAD_ACPI=y
# CONFIG_THINKPAD_ACPI_DEBUG is not set
# CONFIG_THINKPAD_ACPI_BAY is not set
# CONFIG_THINKPAD_ACPI_VIDEO is not set
# CONFIG_THINKPAD_ACPI_HOTKEY_POLL is not set
