Attempts (on a current Lucid beta) to control the screen brightness on
my Dell Studio 1558 fail with the following errors reported in dmesg:

 [ 1162.236365] ACPI: Failed to switch the brightness
 [ 1162.379144] ACPI: Failed to switch the brightness
 [ 1162.538226] ACPI: Failed to switch the brightness
 [ 1162.667358] ACPI: Failed to switch the brightness
 [ 1162.784171] ACPI: Failed to switch the brightness

This is true both for the keyboard's brightness controls (Fn-F4,
Fn-F5) and for a gnome-brightness-applet on the panel.

Output of acpidump, dmesg and lspci is attached.
