I've rebuilt your your rpms via xendom0.src.rpm on another F12 instance.
Xend starts now, but this is the last what i can see on the screen, before it freeze.
I can't get X started when kms is set

   I've tried to load your kernel under Xen 3.4.2 installed via xen-3.4.2.-2.fc13.src.rpm.
It installed kms for Radeon HD 4650 ( high resolution on the screen), xend failed to start
and screen output got frozen before login prompt. Kernel  been built via JF's Git Repo failes with kms for Radeon ( probe error 22) but gets successfully loaded under
Xen 3.4.2 providing stable Dom0 on top of F12.
 Looks like i am missing something trying to work with your rpms.
