Eek, what a strange contraption.. An rtk8139 is a 10/100 Mbit/s *wired* 
ethernet NIC, not a *wireless* one. I doubt that the rtk8139 will ever be
able to handle this; it looks like someone has been *seriously* hacking
about in a non-standard way..

rlphy will not solve your problem. An unknown phy will be picked up by ukphy,
the generic PHY driver. A *normal* 8139 will work "fine" using ukphy, but
this is a completely different matter.

I don't think your card can easily be supported - the best option might be
to get a different wireless NIC. A ral-based 11g cardbus NIC shouldn't be
too expensive, and are common as muck.
