I also tested my Dell 1555 with the kernel of Lucid, but the result is not positive. Although brightness, lid and eject button work correctly, I have problems with the thermal sensors. After resuming the machine, the sensors cannot be read (acpi -t reports 0 C) and thus the fans never start. As a result, the machine overheats and shuts down after a wile.
