I don't know what circutry might be on the backplane, but a hell of a 
lot is on the motherboard.  Regarding NuBus specifically, they have
cranked it up and claim they will offer an interface chip for $25 
to developers (a good idea, if it works out).

On the motherboard (CPU board, I guess you'd call it on a backplane),
there is:
    CPU
    FPU
    DSP + 8KB static ram
    8MB ram (up to 16MB on cpu board) using 1Mb chips (they tried
      to insure that it would work with 4Mb chips, but couldn't try it)
    256KB Frame buffer and grayscale video control
    ICP - Integrated Channel Processor (one of two big "Mainframes on a
      chip", according to The Steve)
    OSP - Optical Storage Processor
      includes ECC, disk controller, also DMA control for laser printer,
      SCC, SCSI, clock, power on/off circuitry

So, yep, it is one incredible f*cking CPU board, no question about it.
