I think many here will probably try to steer you towards either waiting for a 939-pin nForce3-250 setup or towards a 754-pin Asus or Chaintech nForce3 setup.
Abit has lost a few customers with their lack of nVidia nForce3 support.
It's a shame too, they made a DAMN GOOD nForce2 board!
If you want the AGP/PCI lock now, I believe AOpen has that in their nForce3-150 offering.
If you've got to have that setup you listed now, you could certainly do worse. I've heard some positive things said about the Via based KV8.
I'm personally waiting to see some more information roll out about the 35w mobile A64 2700+. :)
