Out of the box, it isn't supported, but the vt82c694 (aka vt694) was supported in v1, IIRC, and the datasheets and I think even the BIOS writer's guide are floating around the internet. If you have experience with C and want to spend some serious time working on it, it would be a relatively easy board to port - relative to many of today's boards, that is. It also should help that the northbridge is very similar to the VT8601 and VT8623, and the SB code should be almost identical to the VT8231.
