I downloaded an unofficial 3.5 update for the BoVD that someone had done. He'd even incorporated the errata. I can't remember where I found it and I can't seem to find it on my hard drive right now. I'd recommend checking Monte's boards or the WoTC boards.
A poster named Nifft has posted unofficial updates of the BoVD stuff on the House Rules boards on this site (IIRC). He's done a great job and I think his work is probably superior to the original.
