Here is the relevant hal output for the macbooks:

udi = '/org/freedesktop/Hal/devices/macbook_backlight'
  info.addons = {'hald-addon-macbook-backlight'} (string list)
  info.capabilities = {'laptop_panel'} (string list)
  info.category = 'laptop_panel' (string)
  info.interfaces = {'org.freedesktop.Hal.Device.LaptopPanel'} (string list)
  info.parent = '/org/freedesktop/Hal/devices/computer' (string)
  info.product = 'MacBook Backlight Control' (string)
  info.subsystem = 'unknown' (string)
  info.udi = '/org/freedesktop/Hal/devices/macbook_backlight' (string)
  laptop_panel.access_method = 'custom' (string)
  laptop_panel.num_levels = 118 (0x76) (int)

So this is probably a bug in hald-addon-macbook-backlight. But the original bug reporter is not using a macbook. If you're having this issue with a macbook, please open a new bug report with 'ubuntu-bug hal' and describe what you're seeing.
