    Another one to check is:

            root=dks0d1s0 # Or whatever is appropriate for your case

    Either explicitly set this, or clear it. If cleared the value will
    be divined from the OSLoadPartition or SystemPartition (I forget which).
    I'd actually lay a small amount of money that this is the problem.

    Been there, been bit by that. It's even more confusing though when
    you have different 6.5.x roots on the same machine, so everything
    comes up fine, but the contents of the filesystem just aren't what
    you were expecting. This has caused some head-scratching on more
    than one occasion.

    Oh, and vfs_mountroot is just the name of the kernel routine that
    tries to mount the root filesystem.

    Hope that helps,
    Brent
