I've got the same problem with a 21041-based card: stock 2.0.24 does not
work at all and instead cycles the port type; 2.0.23 works just fine as
does 2.0.24 with tulip.c from 2.0.23; finally, 2.1.7 (which includes
_almost_ the same changes to tulip.c as 2.0.24) again works fine.
Now, there is a catch here: the difference between tulip.c in 2.1.7 and
2.0.24 is a constant. 2.1.7 has the correct value (as Linus pointed out in
a previous message). This is the patch for 2.0.24 (apply it with -p1):
