Subjecttulip: no link beat, media switching to 10Base2

[a repost of a message sent to the tulip bugtracking system on sourceforge]

I am using the tulip driver from vanilla linux-2.4.4, and when I
disconnect the rj45 from the card I get the following message:

eth1: No 21041 10baseT link beat, Media switched to 10base2.

... and it never switches back (until I ifdown/ifup the interface,
which is mighty inconvenient when I am off-site, which is usually).

Here are the bootup messages in 2.4.4:

Linux Tulip driver version 0.9.14e (April 20, 2001)
tulip0: 21041 Media table, default media 0800 (Autosense).
tulip0: 21041 media #0, 10baseT.
tulip0: 21041 media #4, 10baseT-FDX.
tulip0: 21041 media #1, 10base2.
eth0: Digital DC21041 Tulip rev 17 at 0xf880, 21041 mode, 00:00:C0:D4:74:D6, IRQ 5.
tulip1: 21041 Media table, default media 0800 (Autosense).
tulip1: 21041 media #0, 10baseT.
tulip1: 21041 media #4, 10baseT-FDX.
tulip1: 21041 media #1, 10base2.
eth1: Digital DC21041 Tulip rev 17 at 0xf800, 21041 mode, 00:00:C0:6A:7F:D5, IRQ 11.

There are two identical(-ish) cards in the machine (it is acting as a
router), both the same brand anyway (SMC EtherPower PCI). I was able
to hack in 10BaseT stability in a previous kernel (2.4.1) using
ChangeLog for 2.4.4 that these features were removed. How do I get
reliable 10BaseT operation inspite of possible cabling disconnections.
