Can you collect the complete "lspci -vvvxxx" output (as root) and the complete dmesg log? The first step is to figure out whether the PCI core is enumerating the device. If nothing else works, you could collect the dmesg log with the card removed, then again with the card installed, and diff the two. The PCI core prints at least one line for each PCI device it finds.
