The Thinkpad is on-board:

fxp0 at pci0 dev 3 function 0: i82559S Ethernet, rev 9
fxp0: interrupting at irq 11
fxp0: Ethernet address 00:10:a4:8b:9b:7a
inphy0 at fxp0 phy 1: i82555 10/100 media interface, rev. 4

I'm not certain which Intel card the desktop uses:

fxp0 at pci0 dev 12 function 0: i82550 Ethernet, rev 12
fxp0: interrupting at irq 11
fxp0: Ethernet address 00:02:b3:27:9a:2a
inphy0 at fxp0 phy 1: i82555 10/100 media interface, rev. 4

Another possible variable is what sort of hub or switch the cards are 
hooked to.  I have no idea what my office uses, but it's full duplex to 
fxp0.  (Oddly enough, the ex0 machine (a Dell Precision 410 that 
requires a weird hack to the Ethernet driver -- see PR 11925) can't 
speak full duplex to the same switch.)  My home desktop, which has the 
Intel card, is connected to a D-Link switch.
