     I can't say I'm a fan of this.  I would hope that it goes away
once we get serious about having a stable KABI for modules.  Modules

are.

} kern-XEN3_DOMU.tgz      
} 
} Does each one gets a copy of the "appropriate" (since XEN needs different

     Packing modules with the kernel kinda implies this.

} together with the kernel? And how is the unpacking done?

     This method would require sysinst to "know" what modules go with
which kernel and to setup things accordingly.

Note that i386 includes an additional set of modules for Xen PAE.
