If you overnite the calibration patches to Kevin at Inkjetart.com, you'll probably find the profile in your email the next morning. There are instructions on the site. If you have CS5 be sure to download the Adobe ACPU utility to print the profiles, don't do it through CS5.
Digitaldog, Eric Chan, and others here are capable of making way-beyond-good profiles as well.
Just do it. You won't regret it. It'll change your life and save you time.
But actually, RC gloss and luster papers are pretty generic and it is likely profiles for one will be kinda-sorta in the ballpark for another. The .am1 media files just describe things like paper handling and inkload settings, but have nothing to do with color profiles. You can just use a generic RC media .am1 file, but best to generate one yourself using the Canon Media Configuration Tool. If you decide to do your own .am1 media file, download a generic one (for instance for one of Canon's RC papers) and use the Media Configuration Tool's "Edit" function to see what inkload the manufacturer chose, and use that one...just skip the inkload step when you run the Media Configuration Tool. It'll make sense when you get there.
