On Lenovo IdeaPad Y430 screen brightness can't be adjusted with Fn+Up/Down in GNOME and /proc/acpi/video/VGA/LCD/brightness reports <not supported>

Other stable operating system works fine including Windows XP, Windows 7 (build 7100), Mac OS X 10.5.6 (Hackintosh), Ubuntu 9.04, Fedora 10, Fedora 11

VESA on rawhide doesn't have this problem, but it runs along Fedora 11's NVIDIA kernel driver. On Fedora 11 this works with/without install any driver.

Reproducible: Always

Steps to Reproduce:
1. Upgrade to Rawhide
2. Press fn+up
Actual Results:  
Nothing showed

Expected Results:  
The brightness control shows and adjust screen's brightness control
