I have a M2NPV-VM which has a PCIe 1.0 x16 slot, not to mention a quite
a bit older.  The card worked fine for me, but that doesn't mean it will
for you.  The spec'd speed cut doesn't matter, I get better results from
the 9500 than with the integerated 6150 even without using VDPAU. 
Integrated gpu shares ram, so that didn't help at all.
