Still no luck - I couldn't see any progress even with this patch.
Booting still stops during either of the followings:
if (pci_resource_start(pdev, PIIX_SIDPR_BAR) == 0 ||
pci_resource_len(pdev, PIIX_SIDPR_BAR) != PIIX_SIDPR_LEN)
return;
or
scontrol = piix_sidpr_read(dev0, SCR_CONTROL);
Once the AC Adapter is plugged in, booting continues fine.
