I am going to assume two things for this answer: first you are 
running Windows XP and second you are running the two monitors in a 
dual monitor configuration.

Microsoft has provided an add-on tool to manage/assign different 
monitor profiles to each of two monitors in a dual monitor 
configuration.  You can download it from: 
http://www.microsoft.com/windowsxp/using/digitalphotography/prophoto/c
olorcontrol.mspx

If you run it from the Startup folder it will set the assinged 
profiles for each during the boot sequence.  Be sure to add a /L to 
the command string if you do.  This runs the program in quiet mode.  
Without the parm, the boot sequence will halt when the app runs to 
ask you to assign the profiles.  

For example:  "C:\Program Files\Pro Imaging Powertoys\Microsoft Color 
Control Panel Applet for Windows XP\WinColor.exe" /L

I run the Spyder2 against each monitor and build a profile for each.  
I give each a unique name so that I can assign them to the monitors.

I am running Win XP on a desktop using a dual monitor setup with the 
montors running off a single video card.

I hope this applies to your situation and that it helps,
