some questions about nForce and LinuxBIOS

I don't think anyone's done an nForce2 port for LinuxBIOS. The nForce4
on the other hand might be different, you would have to ask Dr. Lu @
Tyan about that.
And Ron might have just made bootup time <= 8 seconds for K8s. I'm dying
to try this stuff out on my nForce3 :)
