If i have ONLY ONE graphic card, can i passthrou i to a domU?

i has only one graphic card, and i want to passthrou it, but i always
failed, when i execeute:

*echo -n "0000:03:00.0" > /sys/bus/pci/drivers/nouveau/bind*
*echo -n "0000:03:00.0" > /sys/bus/pci/drivers/pciback/bind*
*
*
The terminal promts:
*bash: echo: write error: No such device*
*
*
* *It will succeed when i passthrou some
other device(such as my wireless network adaptor)

Anyone can tell me if i can achive this?thx ahead.
