This card isn't MII-capable AFAICT, which is annoying. I have a similar
card in my desktop at home, but it has 2 RJ-45 jacks: One for 10bT, one
for 100bT. drivers/net/tulip/de4x5.c says you'd feed it
"args=100Mb,fdx" for 100bT full-duplex operation. Try it and see what
you get? HTH,

No luck yet 
Above param format is not accepted, but:
insmod de4x5 args='autosense=TP autosense=100Mb' goes without error
messages and
then dmesg contains ao.:
eth0: media is 100Mb/s
eth0 media is TP.
- BUT - the LED says 10Mb...

Have you considered the possibility that the LED for 100Mb is dead?
One way to check is to connect it to another device which is known to do
100Mb and see if it can communicate at 100Mb with this Tulip. If it can,
ignore the LED...
