After a cold boot I can do this:

root@powertower:/home/jzwolak/download# ./mii-diag -A
10BaseT eth1
 Setting the media capability advertisement register of PHY
#24 to 0x10bb.
Basic registers of MII PHY #24:  1000 786b 2000 5c01 10bb
40a1 0003 0000.
 Basic mode control register 0x1000: Auto-negotiation
 Basic mode status register 0x786b ... 786f.
   Link status: previously broken, but now reestablished.
   *** Link Jabber! ***
 Your link partner can do 40a1: 100baseTx 10baseT.

Also, I can do the above if I disconnect the network card
(from the network) and then reconnect the network card.
