Thank you for your reply.
I didn't know that there is Virtex6 coming with support on 440-based cores! That's a nice info.
At this point in time, Virtex4 (ML 403) is all what I have. It's a bit behind from yours. And i want to play around with this board to work with FreeBSD.
Will it be a lot of work?
I would like to start with some reference. hope you can help me on this.

At the moment, no.

Virtex 4/5 parts have 405-based hardcores, which FreeBSD doesn't yet
support. The Virtex 6 will support 440-based cores, which FreeBSD does
support on Freescale parts. It would still be some work to support
Xilinx's soft-IP peripherals.
I have a Virtex 4 with a 405 hard core, as well as an IBM Walnut 405
eval, so with the recent work by Rafal and co on getting U-boot support
for FreeBSD, maybe something will finally happen on the 405 front.
