Hmm... yes, NetBSD does support VME on Sun4m.

Any device for which there's a machine-independent VME driver for should work.

Specifically noted on the web page are:

     * SCSI interfaces                                                          

          * 5 MB/s NCR 5380 SCSI controller, VME card (Interrupt driven and     
            polled DMA) (si)                                                    

     * VME disk interfaces                                                      
          * Xylogics 7053 VME/SMD disk controller (xd)                          
          * Xylogics 450/451 VME disk controller (xy)                           
                                                                                
            Note: VME/IPI disks are not supported

Does Sun memory for the 670MP actually use the VME bus?  It sure doens't
on a sun-3.

I doubt it, though the 'xbox' is supported.
