I confirm that:
* the bug appeared after a kernel update and nvidia driver installation
* restarting hal removed the duplicate
* udevadm trigger created the duplicate again.
Note also that I had both the wired and wireless card duplicated, but that each operation to remove or recreate the duplicate only workd on 1 duplicate at a time.
I.e. I needed to restart hal twice to remove both duplicates, and I needed to trigger udevadm twice to re-create both of them.
