Backlight off timeout

Hello!

I'm trying to bring our old backlight timeout back to life.

To toggle the backlight, I'm launching pgserver with a specific option :
pgserver --timers.backlightoff=100
(this should be a 10 sec timeout).

Now, in the fbdev.c framebuffer file, I catch the driver messages :
- PGDM_BACKLIGHT=0         (turn off)  
- PGDM_POWER=PG_POWER_FULL (turn on)
and I do an ioctl on the lowlevel framebuffer driver accordingly.

Trouble is, when I start up pgserver : 
1. I immediately get a PGDM_BACKLIGHT event. Not even waiting for the 
   timeout to occur.
2. I correctly get the PGDM_POWER events, but no more any PGDM_BACKLIGHT
   timeout event, even after being idle for a loooong time.

Is the backlight timeout not supported anymore?
Any idea before I dig further into the timers?

I thanks you in advance!
Thierry
