Just to make sure I'm clear on this ... you're saying that unless I have
VT-d, there is no way I'm going to give a fully virtualized guest direct
access to a parallel port of any kind (either on the mobo or on a PCI card).
Do I have that right?

Not quite, for a PCI card yes, you would definitively need VT-d, but there are some exceptions for special devices like serial ports and usb devices. I'm not aware of a special parallel passthrough option but I may have missed that. If there isn't one have you thought about a usb to parallel adapter and passing through the usb device? Afaik James Harper is currently working on an extension of his GPLPV drivers that will cover PVUSB...
