[coreboot] v3 error messages

I can't get v3 for simnow to work with coreinfo as the payload.  I get no
VGA even if I enable it, VGA is never mentioned in the boot log, and it ends
with a triple fault:

cisc-cpu.cpp: CProcessor::GenerateException(): shutdown due to triple fault

Fatal error reached, stopping simulation.  Error message(s) follow:

cisc-cpu.cpp: CProcessor::GenerateException(): shutdown due to triple fault

NOTE:  Simulation cannot be restarted until a reset is asserted.
Simulation state CAN be inspected with the SimNow debugger.

-- end triple fault --

This error shows up in the boot log for simnow 4.4.4pub:
k8_domain_scan_bus
pci_scan_bus start bus 0x0000ce2c, bus->dev 0x0000cbe0
ERROR: pci_scan_bus called with incorrect bus->dev->path.type, path is
PCI_DOMAIN: 0000
PCI: pci_scan_bus for bus 00
pci_scan_bus: old_devices 0x0000cee0, dev for this bus 0x0000cbe0 (domain_0)
PCI: scan devfn 0xc0 to 0xff

It also shows up now in QEMU (it didn't use to.)
pci_domain_scan_bus: calling pci_scan_bus

ERROR: pci_scan_bus called with incorrect bus->dev->path.type, path is
PCI_DOMAIN: 0000
PCI: pci_scan_bus for bus 00

This "Not a multi function device" message is new to QEMU too.
PCI: 00:00.0 [PCI: 8086:1237] enabled
PCI: pci_scan_bus pci_probe_dev returns dev 0x0000b918(dynamic PCI: 00:00.0)
Not a multi function device, or the device is not present. Skip to next
device.
PCI: devfn 0x8
pci_scan_get_dev: list is 0x0008fee0, *list is 0x0000acc0

Has anyone gotten v3 + coreinfo to work on simnow 4.4.4pub?

Thanks,
Myles
