Binary package hint: xorg

I'm using a Dell Latitude E6400 (Intel 4500MHD) with a docking station. When booting up while docked, the external monitor is enabled but using the wrong resolution. When booting undocked and then docking the laptop, the correct resolution for the external monitor cannot be set.
LVDS is the internal display, HDMI-1 is the dvi-output of the docking station.

Using Ubuntu 8.10 beta (updated it today) with xorg 1:7.4~5ubuntu1.

Expected behaviour:
- Boot the laptop while docked, lid is closed
- External monitor is enabled using its native resolution (1600x1200)
- Internal display is disabled

Actual behaviour:
- Boot the laptop while docked, lid is closed
- External monitor is enabled using the internal display's native resolution (1440x900)
- Internal display is enabled

Expected behaviour:
- Boot the laptop while not docked, lid open
- Internal display is enabled
- Close lid, dock the laptop
- External monitor is enabled using its native resolution (1600x1200), internal display is disabled

Actual behaviour:
- Boot the laptop while not docked, lid open
- Internal display is enabled
- Close lid, dock the laptop
- External monitor is not being enabled, its native resolution is not listed by xrandr

So there are three problems:
- When docking/undocking the monitors are not automatically enabled/disabled
- The native resolution of the external monitor is not being listed when docking after an undocked boot
- The wrong resolution is set for the external monitor when booting docked
