I had hvm domU working fine. This problem is specific to my pv-ops
config. I'm not seeing any PCI devices after I bring up the domU. I
was able to get this working as an hvm instance, but not pv.
I'd appreciate if anyone could offer some insight as to why I can't
see the PCI devices in domU.

I've gone through these
http://wiki.xensource.com/xenwiki/XenPCIpassthrough

I sync'd up with Jeremy's 2.6.32x tree and xen 4.0.1-rc3.pre current
as of today.
The hardware is a proliant G5 (intel X58 chipset) with dual i7's.

The dom0 shows these devices available:
 xm pci-list-assignable-devices
0000:17:00.0
0000:17:00.1
0000:14:00.0
0000:14:00.1

0000:10:00.1

0000:10:00.3
0000:0a:00.0
0000:0a:00.1
0000:07:00.0
0000:07:00.1
0000:07:00.2
0000:07:00.3

but the domU see's nothing:
~# lspci
~#

Are there any boot options that need to change from hvm to pv
regarding pci passthrough/iommu settings?
I'm using:

menuentry "Xen osa-dom0 6.0.14-01, linux 2.6.32.15" {
    multiboot /boot/xen.gz dummy=dummy console=com1 115200,8n1

    module /boot/initrd.img-2.6.32.15 /boot/initrd.img-2.6.32.15


Are these messages from the domU boot significant?

[    0.000000] No local APIC present

I'm running the same kernel on dom0 and domU.
I attached the .config, the dom0 kern.log, /var/log/xen/* and the domU
boot is inline below.

To unbind  the PCI devices from dom0 I ran:
