Confirmed for TravelMate 5735z with intel gma 4500MHD on Natty 64-bit.

The problem does however not appear for me if I already use the backlight adjustment keys (fn + left arrow) during the bios boot screen. The backlight adjustment does however not work in natty anymore.

Adding options "acpi_osi=Linux acpi_backlight=legacy" in GRUB (like in bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/518002) enabled backlight adjustment using fn+arrow keys. This also allows for turning backlight back on when encountering a black screen.
