Regression: Pressing and holding keyboard backlight key results in cycling back to max brightness

[Chascon]

Symptoms
The monitor backlight cycles on and off as one holds a sustained pressing of either the darken or lighten buttons. Additionally, the keyboard light also cycles on and off.

Steps to reproduce
Press either the dim or brighten buttons.

Results
The monitor backlight cycles on and off.
The keyboard light also cycles on and off.

Expected results
The monitor backlight and keyboard one do NOT cycle on and off as one presses the corresponding buttons.

Comment
Since this didn't happen in the previous Natty release, presumably using pommed 1.36 (where it was reported have been fixed), but reportedly occurred with version pommed 1.35~dfsg-1ubuntu1 on Maverick Meerkat (as can be testified to from https://bugs.launchpad.net/ubuntu/+source/pommed/+bug/694566), this is a regression.

Specs of Computer affected
Pommed version: 1.39~dfsg-2

Hardware
First generation (2006) Intel MacBook Pro (Intel Core Duo, aka Yonah based processor) with an ATI Mbility Radeon X1600 video card.

Description: Ubuntu 11.10
Release: 11.10

uname -r
3.0.0-12-generic

I've noticed that it seems to work now, as long as there are multiple pressings in a pulsating manner.

The keyboard still lights up unexpectedly towards the end, and shuts itself off again when bring it back up again. Pretty wacky.
