This Bug also effects Ubuntu Maverick Meerkat running on an Acer TravelMate 5735Z and the workaround changing

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=legacy"

in /etc/default/grub works as well.

After updating Grub and rebooting, the (graphical) notification does not appear anymore but the backlight dimming using the Fn keys works.
