This shows that both kernel modules are loaded.  To simplify
troubleshooting please ensure that only the 'mrf' module is loaded and
not 'pci_mrfevr'.

Only one linux driver can be attached to a particular PCI device.  This
will typically be the first one loaded, in this case 'pci_mrfevr'.  I
should also note that, with modern Linux drivers, having to manually
create a file in /dev/ is a sure sign that something is wrong.
