There are standard PCI cards that support VDPAU, but I've not seen any 
low profile ones (not to say there aren't any, just that I have not run 
across them).

Do you have a mini PCIExpress slot? Many small boards have them to use 
for WiFi radios. This would allow you to use a Broadcom CrystalHD 
module, not as well supported as VDPAU, but such support is coming.
