Not only can you hide them in ICS, but you can also completely disable them from running at all.
Open your app drawer, long press on an app you'd like to hide, and and drag it to the top of the screen where it says "More options." Then select "App info" from the pop-up box. From there, you'll have one of two options in the top right hand corner. It will say "uninstall updates" or "disable." If it says "disable," go ahead and disable it. It will now be hidden from your app drawer and it won't run because it's completely frozen. If it says "uninstall updates," go ahead and uninstall the updates. After that finishes, the box will now say "disable."
