Resolution change on monitor close

[Duane Morin]

Ok, here's my latest config problem.  This is a new one.  My LCD, I'm 
told, runs optimally at 1400x1050, which I am using.  When I close the lid 
and reopen it (immediately, even -- not waiting for a suspend or any other 
screen blanking event) it comes back in 700x1050 mode - so "centered" 
boxes are now split down the righthand side, but the bottom nav bar is 
still in place.  I fire up the screen resolution application, reset to 
1400x1050, and it's back to normal.  it's worth noting that the screen res 
app still thinks it is in 1400x1050 mode -- if i run the cursor off the 
right side of the screen it disappears as if I have a virtual workspace 
(though I can't seem to get it to scroll).

I suspect this has something to do with APM power management, which I just 
switched to over ACPI because I was getting random hangs I could not 
account for.  Can anybody draw me a stronger connection than that?
