 The SUN V20z  Uses the  AMD8000 series chipset.  To be exact,
it uses  the  AMD8131 HyperTransport to PCI bridge and the
AMD8111 to communicate with keyboard, USB, CD/DVD and Mouse.

This is the same general chipset as the Tyan boards.
Maybe the above options for nforce3 are wrong in this context.
