I don't see :loaded or :loadfail as useful, but the concept of :loading 
is slightly different and could actually be useful.

The object element has a standby attribute [1] (although it's a 
<standby> element in XHTML2 [2]) which is designed to be shown by user 
agents while the content is loading.  Perhaps a :loading or :standby 
pseudo-class could be used to select elements in this state.

eg. For (X)HTML 4.01/1.x:
   object[standby]:standby { content: attr(standby); }

Would select any object with a standby attribute that is in the :standby 

   object:standby *:not(standby) { display: none; }

would remove all content from the display except the standby element 
from an object in the :standby state.
