this is actually caused by a BIOS bug/kernel bug (depends who you talk
to). It's because the BIOS has tables in the DSDT to represent the

I can confirm that, as you say, "the amount of brightness 'hops' in my case
have varied from 2 to 4 steps for a single Fn+Up/Down press".
However it seems to me that the number of brightness hops also vary when a menu
is open. The only differ
I have noticed something interesting..
When a menu is open (Applications,Places or Systems), and Fn+up/Fn+down keys
