When did this bug appear? Did you ever try some earlier versions of
xserver-xorg-video-intel 2.x?
Up until recently we'd just been happily using a stable build of Etch. Now with the promise of various new features I'm looking into updating our standard build to be Lenny, when it is released. So I'm afraid this is the first test I've done since Etch. If you have any forward-ports I'd certainly test them.

disconnected? I would say "connected" given the log below. Are you sure
you didn't mess up the xrandr outputs?
I agree this is weird and so was careful with my xrandr outputs. And I have just now, as below, double checked.
# system boots with only top part of screen primarily used and I log in to gdm/gnome
local@pc20:~$ grep connect /var/log/Xorg.0.log
(II) intel(0): Output VGA connected
(II) intel(0): Output TMDS-1 connected
(II) intel(0): Display plane A is now enabled and connected to pipe A.
(II) intel(0): Display plane B is now enabled and connected to pipe B.
(II) intel(0): Output VGA is connected to pipe A
(II) intel(0): Output TMDS-1 is connected to pipe B
local@pc20:~$ xrandr | grep VGA
VGA disconnected 1280x800+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
local@pc20:~$ xrandr --output VGA --off
# gnome begins to use the full screen and bottom taskbar drops to bottom of the screen
local@pc20:~$ xrandr | grep VGA
VGA disconnected (normal left inverted right x axis y axis)
