I've got everything stuffed in a Silverstone LC17 case (6 hard drives), which means I only have 1 PCI slot where I can physically put the cards.  The other PCI slots are useless for larger cards because the hard drives protrude so far back on top of the motherboard.

There are, iirc, both 3.3v and 5v PCI slots. Its entirely possible that the
PVR-500 requires a 5v slot, and at least the slot you're using right now is
only capable of delivering 3.3v. That's about the only thing I can come up
with anyway, if the F14 GA kernel (the one on the live CD) works on your old
backend just fine, but not in the new one. That, or some other quirk with
the new board that the card doesn't like for some reason. Dunno.
