Default Laptop + Monitor display, how to configure?


I have an Asus A6JC laptop computer with a Nvidia Go 7300 card. The laptop has a built-in LCD display and two external display connectors: D-Sub and DVI. I also have a 24" 1920x1200 display which I plug in into the laptop whenever I'm at home. What I'd like to have is the following:
1. Whenever X starts with the 24" display connected to DVI, the DVI is the main display (with it's default resolution, preferably auto-detected) and the laptop's LCD is off.
2. Whenever X starts without any displays, it uses the laptop's LCD with it's natice 1280x800 resolution
3. Whenever X starts with a device plugged into the D-Sub port, it outodetects the device and uses is as a secondary display, as a clone of the LCD display.

So far I've managed to configure TwinView so that 2 is satisfied and 1 is partly satisfied (the notebook's LCD clones the main 1920x1200 display). My current configuraiton is:
Identifier     "Screen 1"
Device         "GeForce Go 7300"
Monitor        "Panel"
DefaultDepth    24
Option "DPI" "98 x 96" # DPI goes berserk
Option "TwinView" "true"
Option "RandRRotation"
Option "EnableACPIHotkeys" "true"
Option "SecondMonitorHorizSync" "30.0-121.0"
Option "SecondMonitorVertRefresh" "48.0-160.0"
Option             "ConnectedMonitor" "DFP, DFP"
Option         "TwinViewXineramaInfoOrder" "DFP-1, DFP-0, CRT-0"
Option  "MetaModes" "DFP-1: nvidia-auto-select, DFP-0: 1280x800; DFP-1: nvidia-auto-select, DFP-0: NULL ;DFP-0: 1280x800 , DFP-1: nvidia-auto-select ;  DFP-0: 1280x800, CRT-0: 1600x1080; DFP-0: 1280x800, CRT-0: 1360x768; DFP-0: 1280x800, CRT-0: 1280x720; DFP-0: 1280x800, CRT-0: 1024x768; DFP-0: 1280x800, CRT-0: nvidia-auto-select; DFP-0: 1280x800, CRT-0: NULL"
Option  "MetaModes" "nvidia-auto-select; nvidia-auto-select"
Option "Xinerama" "on"
Option "TwinViewOrientation" "Clone"
Option     "SecondMonitorHorizSync"   "UseEdidFreqs"
Option     "SecondMonitorVertRefresh" "UseEdidFreqs"

Default Re: Laptop + Monitor display, how to configure?

Start with nothing extra connected, after You're logged in, attach what You need, go to nVidia control panel and click detect monitors. After that, click configure etc, etc, etc.
Here You go!

What really pisses me off, is when You do disconnect monitor from such a config just by pulling your cable out and didn't do configure -> disabled and only then take out the cable, opengl apps start to go crazy, they don't really know that there is no second monitor at all!!!
Can this be fixed?
