This statement is not true. I got confused because the only the first 
event channel shows up in xm list --long.
The real issue is the hard coding in:

xen/include/public/io/ioreq.h:

#define IOPACKET_PORT   2

This was true before your changes went in. After your changes, xen 
started sending IOPACKET events on:
<EventChannel dom1:0:19 dom2:5:2>

but the user space device models were listening on:

<EventChannel dom1:0:20 dom2:5:3>

However, if I subtract -1, everything magically works :)

I think the quick fix is to redefine IOPACKET_PORT to be 3. Will send a 
patch to remove the hard coding ASAP.
