bertha8it's post made me reevaluate my assumptions.

On a dualhead AGP card under Windows XP you do need to use the windows
 control panel color applet loader in the startup folder (wincolor.exe
/L) to avoid manually chosing profiles. It lets you chose correct
profiles on startup without the need for manual correction.

I was wrong stating that colorvisionstartup.exe does the same thing
for an AGP dualhead card. So dual monitor calibration will still work
but it will require a couple more steps configuring the applet. I
believe xun wang has a PCIe card, so he is in a better situation than us.

Good news is that PCIe cards don't not have that problem...
