If the device isn't even showing up at all in /sys/bus/pci/devices, my first question is "Convince me that your PCI device is in fact functional and plugged in all the way". If it can't even get its slot/function number and vendor/card codes right, it's most likely either mis-seated or dead. I can't remember the last time I saw this caused by a software problem - even devices that don't *have* a driver will at least show up as an unknown PCI device.
