You can probably make the name permanent with udev rules.
See in
you should have permanent-cd and permanent-net rules files which you can 
look for examples. Add a new .rules file with your own rules.

For an USB device it may look like (on an single line)

SUBSYSTEM=="usb", ATTR{idVendor}=="0000", ATTR{idProduct}=="0000", 

I am not sure how it will be for a PCI card, I am not an udev expert, see 
man udev for more informations.
