At the end of this message - together with the output of vortex-diag.

What irritates me is:

Options: force full-duplex.
  Vortex format checksum is incorrect (0086 vs. 10b7).
  Cyclone format checksum is incorrect (0x16 vs. 0x3f).
  Hurricane format checksum is correct (0x3f vs. 0x3f).

Note that I haven't fiddled with that card at all. Plain, bulk 3com card,
dropped out of the bag into the system.

  modprobe 3c59x debug=7
  modprobe 3c59x debug=99

Same result - none.

The cheapest 10/100 repeater hub around.

 You have link beat, and everything is working OK.
 Your link partner advertised 40a1: 100baseTx 10baseT.
