Btw current xen-unstable (upcoming Xen 4.0) doesn't need the "disable FLR" 
patch, 
it has an option you can use to overcome this:

http://lists.xensource.com/archives/html/xen-devel/2009-12/msg00682.html

"Actually we have such a xend option in the xen-unstable tree:
The option is at the end of /etc/xen/xend-config.sxp: 
(pci-passthrough-strict-check yes). Uncomment it and change it to no and
do a "xend restart".
