[ltp] Anyone else fix a problem with a "blinking" fglrx driver?

[Guarded Identity]

You right... 

I set my aticonfig to automatically adjust the power state upon AC on-line and 
off-line ACPI events, and the blinking doesn't seem to occur with that.

Somehow, though, it blinks when aticonfig is manually called... which honestly 
doesn't make any sense to me.  The /etc/acpi/fglrx-powermode.sh is pretty 
short.  Maybe it has something to do with the XAUTHORITY stuff the script 
does.  

Either way, the blinks occurs at other times for sure... not just when the GPU 
switches to another power state.  

I /was/ wondering, though, if it might be some weird interaction with 
tp_smapi.  I do use tp_smapi's force_discharge option with a little daemon 
I've set up to emulate "stop_charge_threshold" on my T42.

I'll probably just stay the course for now.  Other than this blinking... 
everything seems fine, and the power management of the fglrx driver seems 
pretty intelligent, so that's good.  I think I can get down slightly farther 
than before (with dynclock'ing).  

Thanks for the response,
Sukant
