You can disable the system keyboard shortcuts with: 

#import <Carbon/Carbon.h>

void *oldHotKeyMode = PushSymbolicHotKeyMode(kHIHotKeyModeAllDisabled);

Make sure that you re-enable them with: 

PopSymbolicHotKeyMode(oldHotKeyMode);

Be careful if you do this, it makes it more difficult to switch away from your app with Cmd+Tab if it is misbehaving so it can mean that if your app misbehaves the user has to power off the system instead of just force quitting your app.

Tested and working with Mac OS X Lion.
