I am running Ubuntu on an HP Pavilion dm4-2070us, and I can confirm that this bug still exists in 12.04 x64, up-to-date. At boot, the splash displays appropriately. Once the login screen comes up, however, the screen's brightness is reduced to zero. This problem affected me when running 11.04 and 11.10 as well.
