Hi, i debugged into the VGA init code... it seems that the device (PCI: 00:02.0) is not assigned a ROM address. Further debugging into pci_get_rom_resource and pci_moving_config32 shows that pci_read_config32 _always_ reads a 0 from the ROM BAR, even if 0xffffffff is written just before reading...
Any ideas? I will try to find out what v3 does for the qemu VGA device...
