I think I found a little bit better solution: instead of disabling features of gnome-power-manager (step #3 in comment #17) just add "acpi_backlight=vendor" to the same line of grub config (and don't forget to do "sudo update-grub2" after that). Works for my Asus Eee PC 1005PE (even the panel with brightness slider appears while pressing Fn+F5/F6 after that).
P.S. I found solution (originally for Gateway netbook) here: http://ubuntuforums.org/showthread.php?t=1331709
P.P.S. Original solution suggest adding "nomodeset" too, but in my case that severely crippled video performance, so I've just removed it and everything works fine
