  Log:
  Workaround to prevent VMware from melting down. The pseudo PCnet interface
  in VMware reports 0x00000000 in the PCI subsystem ID register, but
  0x10001000 when you read the mirror registers in I/O space. This causes
  pcn_probe() to think it's found a card in 32-bit mode, and performing
  a 32-bit I/O access makes on a 16-bit port makes VMware go boom. Special
  case the 0x10001000 value until somebody at VMware grows a clue.
