I don't think it's quite this hard. For a Linux domU, here are the lines I add to export the com port to my domU:
irq=[ 4 ]
ioports=[ "3f8-3ff" ]
For the Windows HVM domU end of things, it's been a while since I did it, but I'm pretty sure just adding the following got me the necessary access to the com port:
serial="/dev/ttyS0"
My servers don't support VT-d and I'm not running Xen 3.2. As far as USB devices go, I'm not sure, but my example domU files have things like "usbdevice='xxx'" - I'm not sure what types of USB devices you can push through, maybe just the default mouse and tablet support.

This is my understanding:
You need Xen 3.2+, VT-d capable hardware, and PCI passthrough, and
probably a PCI-e serial adapter or a PCI-e USB adapter with a USB to
Serial dongle. VT-d won't let you pass through a legacy (non-Express)
PCI device without passing all of your other legacy PCI devices behind
the same bridge.
It's a shame that it isn't possible to pass USB or Serial devices
without VT-d.
I plan to get a PCI-e USB controller and a VT-d capable motherboard soon.
I hope someone proves me wrong!
