Brightness control on HP laptop does not work with ubuntu-proposed updates

[Don Owen]

Ubuntu Version: 8.10 x64 w/ Proposed Updates

With a clean install of Ubuntu 8.10, the Function (Fn) buttons on my laptop (an HP dv6565us ) work for triggering brightness increase and decrease (Fn + F7/F8). Once updates are installed (through ubuntu-proposed) the brightness controls do not work. Also the power manager does not seem to have an effect.

Xev reports this on Fn + F7 (brightness decrease):
KeymapNotify event, serial 59, synthetic NO, window 0x0,
    keys: 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
           0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
(similar for Fn + F8)

This is a particularly vexing issue as it significantly reduces battery life and seems to be a regression.

I would like to help, so please let me know what I can do.
