Have you tried anything else than FreeBSD 9.0 on this board? I ask because I have a E35M1-I which seems to have the same chip:
tingo at kg-f3$ pciconf -lv | grep -A 4 re0
re0 at pci0:4:0:0:	class=0x020000 card=0x84321043 chip=0x816810ec rev=0x06 hdr=0x00
    vendor     = 'Realtek Semiconductor'
    device     = 'Gigabit Ethernet NIC(NDIS 6.0) (RTL8168/8111/8111c)'
    class      = network
    subclass   = ethernet

and this one runs FreeBSD 8.2 without problems:
tingo at kg-f3$ uname -a
FreeBSD kg-f3.kg4.no 8.2-RELEASE-p7 FreeBSD 8.2-RELEASE-p7 #0: Thu May  3 12:22:17 PDT 2012     jpaetzel at build.ixsystems.com:/home/jpaetzel/8.0.4-RELEASE-p2/obj.amd64/build/home/jpaetzel/8.0.4-RELEASE-p2/FreeBSD/src/sys/FREENAS.amd64  amd64

(disclaimer: this is a FreeNAS box)
and I regularly push large amounts of data (via scp) to it - it is my backup machine.
