I think I may have found the reason that my wlan0 interface was not renamed,
although I don't fully understand why it may be so. It seems that my wireless
interface is treated as a USB device, not a PCI device, despite the hardware
being on a pci-express controller. From lshw:

It may be that the steps for renaming explained here:
http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames
are followed through by udev and item 5 is applied to the wireless card.
Does this sound plausible?
