[X4U] Screen dimming on iMac G5

[Matt Gregory]

I don't know about the iMac, but my PowerBook has an option to dynamically 
set the screen brightness based on the ambient light. Not sure if it's there 
on the iMac, but it's another thing that can mess with the brightness. And I 
imagine it wouldn't kick in until after the grey apple logo screen. So maybe 
something to check.

HTH,
matt.
