As far as I know the only passthrough implemented in VBox is for disk drives.

As I said on the QEMU list, it's not far from a PCI passthrough except the device isn't exposed itself on the bus.

There doesn't seem to be much discussion even on PCI passthrough on the mailing list:

If you are interested in doing it, it might be nice to joint development with QEMU at least on the driver side of things.

I'm sure Bochs had PCI passthrough at some point.

Some pointers:
