     I pulled the boot logs from one of the machines:
 
  1:  Dec 21 22:41:54 zip /kernel: de0: enabling 10baseT UTP port
  2:  Dec 24 22:17:56 zip /kernel: de0: enabling 10baseT UTP port
  3:  Dec 25 23:44:11 zip /kernel: de0: enabling 100baseTX UTP port
  4:  Dec 25 23:47:26 zip /kernel: de0: enabling 10baseT UTP port
  5:  Dec 27 18:16:04 zip /kernel: de0: enabling 10baseT UTP port
  6:  Dec 27 18:31:29 zip /kernel: de0: enabling 100baseTX UTP port
  7:  Dec 27 18:32:38 zip /kernel: de0: enabling 10baseT UTP port
  8:  Dec 28 10:49:38 zip /kernel: de0: enabling 10baseT UTP port
  9:  Dec 30 14:28:42 zip /kernel: de0: enabling 10baseT UTP port
 10:  Dec 30 14:45:35 zip /kernel: de0: enabling 100baseTX UTP port
 11:  Dec 31 14:01:08 zip /kernel: de0: enabling 10baseT UTP port
 12:  Dec 31 14:40:58 zip /kernel: de0: enabling 10baseT UTP port
 13:  Jan  2 17:18:36 zip /kernel: de0: enabling 10baseT UTP port
 
     Lines 3-4, 6-7 show two instances where an immediate reboot
 enabled the correct speed.  In all cases, the machine was plugged into
 the same 10baseT port of the same hub (which itself runs into a
 10baseT port on our etherswitch).  Packet collision rate on zip is
 about 25%.
