Subject: 945gma display blank after power failure regression

Hello,

I have kernel 2.6.37  and an
Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated 
Graphics Controller (rev 03)
in an asus s96f laptop. The battery is shot so it doesn't stay up for a 
second on a power failure. I have
recently started experiencing a problem where if the display has been 
blanked by KDE because of
being idle and I have a power failure then when the laptop boots up I 
have a completely blank display.
I wait till I think it is up and do a blind login as my KDE session 
starts up it turns on the display.

When is it booting I don't see anything - not the bios screen nothing. 
This is very disconcerting.
The first time it happened I thought my lcd panel had died.

Any ideas on how to keep this from happening. I don't think this 
happened on previous kernels.

Thank,
Steve
