Here is my experiences with kernels and devfs :
    
    In the kernel commandline, root=/dev/<oldname> but once the kernel
    is running you can use the new names.  (I don't get it, but it is
    the only thing that works)

    I got the above error when I forgot to inlcude the IDE chipset
    driver in my custom kernel.  Enabling that driver made my problems
    go away.
