en0 at sbus0 slot 1 offset 0x0 level 2 level 1 level 2 level 3 level 4 (ipl 5) level 5 (ipl 7) level 6 (ipl 8) level 7 (ipl 9)
en0: ATM midway v0, board IDs 0.16, Utopia (pipelined), 2048KB on-board RAM
en0: maximum DMA burst length = 64 bytes (must align)
en0: 55 32KB receive buffers, 8 32KB transmit buffers allocated
en0: End Station Identifier (mac address) 00:00:00:00:00:00

Is that correct ?  I've never seen anything produce output like that first
line before on SBUS...also should the mac address be something else but
all 0's ?
