Unfortunately, this is no going to work. The VGA BIOS still use the legacy IO ports. All you will get in the listing is in/out to port 0x3xx. You just have to figure out how to forward IO to legacy ports.

If you snoop the PCI bus right on the PCI slot for the graphic card, you see "real" pci i/o cycles bound to the PCI i/o BAR of the graphic card. If the address is outside of the BAR the access will not be decoded byte graphic PCI agent, I would think. -jf simon
