Description of problem: It appears to be needed for proper backlight support. While it has the "acpi*:LNXVIDEO:*" alias, that doesn't seem enough to get it loaded on my Thinkpad T60. Version-Release number of selected component (if applicable): kernel-2.6.25-0.121.rc5.git4.fc9.x86_64
Dumb question... does your T60 have that device listed in its ACPI tables?
No, nothing in /sys/bus/acpi that would match that.
should be fixed by 5c9fcb5deef4d3a49798d76c48b726d2e3c7df72, commited upstream 27 March
