3.6.11.6 stable review patch.
If anyone has any objections, please let me know.

[ Upstream commit c8f6d8351ba8c89d5cd4c562552ec7ec29274e31 ]

Like on UL30VT, the ACPI video driver can't control backlight correctly on
Asus UL30A. Vendor driver (asus-laptop) can work. This patch is to
add "Asus UL30A" to ACPI video detect blacklist in order to use
asus-laptop for video control on the "Asus UL30A" rather than ACPI
video driver.
