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.
