RealTek 8139 not identified in FreeBSD

[marlon at freemail.gr]

Hello.

I have an Acer Aspire 1600 laptop with a RealTek 8139 integrated network card.
The card is not identified at all in neither FreeBSD 6.1-RELEASE nor in
FreeBSD 5-STABLE, not even in DragonFlyBSD (which is a fork of FreeBSD 5 IIRC).
"pciconf -lv" does not report back any information on the card at all.

Linux and Windows however can identify the card as "RealTek 8139 chip type
'RTL-8100B/8139D' at 0x1800-0x18ff, Memory: EC005000-EC0050FF, IRQ 19".

Since FreeBSD is a lot better for my computing needs, is there a way I can
get the above card to work correctly (or even work at all) in FreeBSD?

Thanks in advance.
