As John said, there is no driver for SiS190/SiS191 gigabit
controller. Accoring to .INF file of Windows driver from vendor the
hardware supports Tx/Rx checksum offload, jumbo frame as well as
WOL. Linux have a driver for these controllers but the code has
lots of magic registers and hardcoded magic parameters so it's very
hard to understand what the magic value really means. So I guess
Linux also lacks documentation for the hardware and they may have
spent hardtime to make it work. 

Maybe the last resort in FreeBSD would be ndis(4). I don't have
SiS190/SiS191 hardware so I don't know whether ndis(4) works or not
but you can get help from weongyo@ for ndis(4) issues.
