I have the exact same mobo with 405 chipset and the exact same problem. The lastest ForceWare 15.0 drivers don't work either. So despite all the Vista ready logos on my mobo's box I can't even get on the internet to register the !@#$ thing.
I popped in a Fedora Core 6 DVD instead and it detected my NIC during setup, allowing me to add some programs from the "extras" repository before first boot even. It also detected and installed drivers for my five year old Hauppague TV card which Vista still doesn't recognize.
If only Windows was as easy to install as Linux.
