Xv is only useful if you want the graphic card to do scaling for you.
Moreover, for QEMU, it's only interesting if the card exports a RGB visual
for you (which is the case of the NVIDIA drivers but not, last time I
checked, on some ATI drivers in XFree).

If you display the graphic 'as is', I do not see why Xv should be faster
than plain XShm.
