Im posting this here just to keep the question/answer in archive,
someone will probably have similar problem.
It is an extract of the DragonFly chat channel today earlier.

	<Sdav_>	hello, i just bought a realtek 8139 card but it is not
detected (it was not detected with FBSD neither, because the vendor id
was not recognized) where should i add this vendor id to use rl driver
on it? same place than FBSD? thanks for any data.
	<swildner>	Sdav_: what are the ids?
	<Sdav_>	none0@pci0:8:0: class=0x020000 card=0x00000000
chip=0x81391904 rev=0x01 hdr=0x00
class = network
subclass = ethernet    // extracted from pciconf line command
	<swildner>	yea that's not in if_rl.c
	<swildner>	it's not supported yet.. the id is not in if_rl.c
	<Sdav_>	i had another rl8139 before that worked, but this one is not working.
	<swildner>	Sdav_: *here was an url, i will just pasted the code here:

Hi,

can you test:

http://leaf.dragonflybsd.org/~swildner/sln2.tbz

I did the basic porting (get it to compile) and sephe enhanced it a bit. 
It could work now, or not. :)

This may be the "Rsltek 8139D" (I am not wrong on the name ;) or
something similar to Silan's 92301?  It's quite different from
Realtek's 8139.  You can first try your luck with rl(4).  If it did
not work, I could do a quick "slash" porting of a fbsd4 driver (the
fbsd4 driver was published by Silan in public domain?) or do you want
to port that driver :)?

Best Regards,
sephe

I found a little inscription in the board saying "8139d" so, i guess i 
will have to use the new driver.
I doubt about been able to port a driver by myself, im not there yet, 
but if you can point me to some documentation i will try :-)
Thanks for the info.

Hi,
I'm looking into porting the old FreeBSD 4.7 driver from Silan at the 
moment. Let's see what I have in some days. :)

Sascha has made very good progress to make the fbsd4 driver working,
please stay tuned :)

Best Regards,

Of course this patch was just for testing and if it works the device 
should/will be added to pcidevs.
