Andrew, Jarod,

The PVR500 works fine with the F14 x86_64 Live CD on my old backend which
was running CentOS 5.

The ivtv-related output from dmesg is here:
http://pastebin.com/NZhzPUyK

The start of the differences is where the old backend boots and says it's
changing the "unreasonably low" latency timer from 32 to 64.  On my new Core
i5-based backend, it says the following:

tveeprom 4-0050: Huh, no eeprom present (err=-6)?
tveeprom 4-0050: Encountered bad packet header [a8]. Corrupt or not a
Hauppauge eeprom.
ivtv0: Invalid EEPROM
cx25840 4-0044: Unable to detect h/w, assuming cx23887

The system power supply should be sufficient.  It's a Seasonic 80+ Gold
certified 650W power supply.  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.
