setting 100baseTx-FD

Hi all.  I've got an ethernet card based on the Digital 21143 chipset and
I'm using the tulip.c:v0.91g-ppc 7/16/99 driver (kernel 2.2.14 on a red hat
install).  Recently my dorm's network was upgraded to 100baseT ethernet so
I thought it might be nice to take advantage of this.  So I brought down the
network interface and removed the tulip kernel module.  Then I ran

insmod insmod /lib/modules/2.2.14-12/net/tulip.o options=5
/etc/rc.d/init.d/network start

But tulip-diag -e still reports a 10mpbs connection:

tulip-diag.c:v2.00 4/19/2000 Donald Becker (
Index #1: Found a Digital DS21143 Tulip adapter at 0x2000.
 Port selection is 10mpbs-serial, full-duplex.

  Internal autonegotiation state is 'Negotiation complete'.

while mii-diag reports:

Using the default interface 'eth0'.

 Basic mode control register 0x1000: Auto-negotiation enabled.
 You have link beat, and everything is working OK.
 Your link partner advertised 45e1: Flow-control 100baseTx-FD 100baseTx 
10baseT-FD 10baseT, w/ 802.3X flow control.

What am I missing or doing wrong?  How can I tell my card to run at 100baseT?
Any suggestions?  Thank you.
