I was under the impression that 5.4 (2.6.18-128.el5) did not have
the pciback module.  Either way, I  would recommend you use the
pv-ops [1] and try that one. If you still have trouble with the pv-ops, please
include more details: dmesg of both DomU and
Dom0, lspci -vvv of both domains, and boot your Xen with guest_loglvl=all

I am reading this as, it fixed the warning about the device not being safe,
but did not help with your Dom0 hang?
