The listings I find are with laptops with Integrated Realtec 8139 nics
Your post shows an 8139too in both your lsmod and /proc/pci Surely these links to the 8139 continue to show up in lsmod and /proc/pci even with the cardbus card removed from the system, yes ?
My guess is that your computer does indeed have a realtec 8139 nic somewhere in it..
Your card looks to be the Digitus DN7001G Cardbus 54MBps WLAN card.
