Not sure if you already found this answer somewhere else, but I found this article...the link for the entire article is...http://www.computer-darkroom.com/ps12_colour/ps12_1.htm  I was also looking for the same thing, but I guess Adobe no longer provide Monitor Calibration...

Section 2 - Monitor Calibration and Characterisation

Monitor calibration and characterisation (profiling) is probably the most important aspect of a color managed workflow; yet many users seem oblivious to issues poor monitor calibration, etc can have on their documents. So, what is calibration, why is it so important, and why is it different from characterisation?

Calibration is a process whereby a device is brought to a standard state (e.g. a color temperature of 6500K and gamma of 2.2), whereas characterising the monitor is the process of determining how the monitor represents or reproduces color. We characterise the monitor by measuring how it displays known color values, then creating an ICC profile. The ICC profile is simply a data file that includes a description of the monitorsí color handling characteristics (i.e. its gamut). The calibration data will also be written into the ICC profile. As I've already mentioned, Photoshop then uses the monitor profile to automatically optimise the display of documents. It does so by carrying out an on-the-fly conversion between your document profile (e.g. ProPhoto RGB, Adobe RGB, sRGB, ColorMatch) and your monitor profile. This conversion does not alter the actual document in any way; just its appearance on the monitor.

Adobe stopped shipping Adobe Gamma with the Mac version of Photoshop a few versions back, but for a while kept it for Windows. This was because there was no software only alternative. Since Apple Display Calibrator Assistant was still installed within System Preferences Mac users never really found the absence of Adobe Gamma to be a problem. However, given that Windows Vista and Windows 7 don't play well with certain utilities, it was inevitable that Adobe Gamma would eventually be dropped from the Windows version of Photoshop. So, it came as no surprise that as of Photoshop CS3 Adobe stopped shipping Adobe Gamma, and it's still absent from CS5. For what it's worth, I think we can safely assume that Adobe will never again ship a monitor calibration utility with Photoshop.

Obviously, software only monitor calibration applications use the human eye to determine tone and color differences between a series of white/grey/black/color patches. However, it  should go without saying that the eye isn't the most accurate method of measuring these differences. Therefore, my recommendation would be to use a hardware based system such as the DatacolorSpyderPro3, X-rite Photo ColorMunki or X-rite Photo i1 Display 2.

Tip for Mac OS X users: a tutorial describing the process of calibrating a display with the Apple Display Calibrator Assistant can be found here.

Useful Information on location of  ICC/ColorSync Profiles

Photoshop CS5 is only compatible with Windows XP with Service Pack 3, Windows Vista or Windows 7 on the PC platform and OS X 10.5.7 or higher on the Mac platform. The upside of this is that the ICC and ColorSync profiles are more easily found.

Profile locations:-

• Windows XP, Vista and Windows 7 - sub-folder named Windows\system32\spool\drivers\color

• Mac OS X - ColorSync profiles are generally located in either the Library/ColorSync/Profiles or Users/~/Library/ColorSync/Profiles  folder
