If you were talking about the general iretq => INTERRUPT_RETURN, then the answer is "Yes, they are sufficient". The first version of lguest ran the guest kernel in ring 3 (using dual page tables for guest kernel and guest user). The current version I'm pushing runs lguest in ring 1, and the entry.S code worked for both.
