The graphical boot screen opens a text window and you're presented with the 
actual boot messages if any service fails to start. Successful boot messages 
are hidden and the user sees a pretty startup screen.  Failed boot messages 
are already displayed as expected so the user can take whatever action is 
necessary to correct the failure.

At least this is the default behavior of my FC1 system.  I can't imagine that 
FC2 behaves any differently.
