I would disagree that the trusted loader is a point of failure. It is 
not trusted in the sense that we need to trust its code to behave 
correctly, all we need is to trust it as not being malformed data that 
can trigger an exploit in the domain builder, and of course it is not, 
given that it is supplied by you the admin and not by a (potentially 
hostile) user.

Anyway, this code is already written for Xen 1.3. You can find it at
