Interesting.  I have come across 2 motherboards now that have onboard 
Realteks of some sort, similar to what you see. In the PCI conf below, rl0 
is the onboard and rl1 a PCI version.

rl0_at_pci1:4:0:   class=0x020000 card=0x813910ec chip=0x813910ec rev=0x10 
hdr=0x00
     vendor   = 'Realtek Semiconductor'
     device   = 'RT8139 (A/B/C/813x/C+) Fast Ethernet Adapter'
     class    = network
     subclass = ethernet
rl1_at_pci1:5:0:   class=0x020000 card=0x813910ec chip=0x813910ec rev=0x10 
hdr=0x00
     vendor   = 'Realtek Semiconductor'
     device   = 'RT8139 (A/B/C/813x/C+) Fast Ethernet Adapter'
     class    = network
     subclass = ethernet


Yet, one works as expected, the other half works in that the switch sees a 
lot of FCS errors as if there were a duplex mismatch, despite both sides 
being autoneg. (I tried various manual configs as well on both sides 
without change). This is on stable, but the same problem was happening on 
CURRENT when I tried to see if the re driver would see it, it did not.  The 
only difference I see from your NIC and mine are the revs, yet the onboards 
on the 2 motherboards I have refuse to work without generating lots of errors.
