I just upgraded to newly released Xen 3.3.1 hypervisor but unfortunately it
didn't seem to help with my problem.. I still get the exact same errors with

I don't think the problem is ata_piix, I've tried the pv_ops dom0
kernel on a Dell Optiplex 755 and unbranded system with gigabyte
motherboard, on both systems none of the storage devices worked,
including ahci, ata_piix, I even tried putting the root filesystem on
a usb storage device but that too is broken, I think interrupt routing
is not working at all perhaps?
I'm going to do more testing this weekend...

Hello.
I just did some more testing too..
I upgraded to the latest patches for Linux 2.6.29-rc1-tip
log of xen+kernel from serial console:
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-bootlog-5-xen331-linux-2.6.29-rc1.txt
(XEN) Command line: dom0_mem=1024M loglvl=all guest_loglvl=all com1=19200,8n1 
console=com1
Kernel command line: ro root=/dev/vg00/lv01 console=hvc0 earlyprintk=xen 
pci=nomsi
And the failing part of the log is here:
xen_allocate_pirq: returning irq 30 for gsi 18
xen_set_ioapic_routing: irq 30 gsi 18 vector 160 ioapic 0 pin 18 triggering 0
