No TX on 905B (cyclone) using 0.99H

Please help.
I'm really having trouble getting my 3c905B Cyclone to work on a
10baseT network. I'm using the latest 0.99H driver and kernel 2.0.35.
I'm also using the S.U.S.E distribution of linux with an ATX
motherboard. I'm at a loss here.
I've already looked through the archive of vortex-debug and really
found no suitable answer. I've done the following to try to get it to
work:
1. disabled PnP in the bios
2. switched the 3c905B to another PCI slot
I'm still getting the same problem which is that apparently I can't
transmit. ifconfig eth0 reveals that RX increases but TX doesn't.
The first sympton when the system boots that the thing is not working
is when '/sbin/init.d/route start' is executed by init setting up the
default route.
A 'route add default gw 192.190.254.1' gives:
SIOCADDRT: Network is unreachable
I always get a network is unreachable error for anything like ping,
telnet, etc.
The ifconfig eth0 gives:
eth0 Link encap:10Mbps Ethernet HWaddr 00:10:5A:11:13:5F
inet addr:192.190.254.25 Bcast:192.190.254.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:1710 errors:7 dropped:0 overruns:0
TX packets:0 errors:0 dropped:0 overruns:0
Interrupt:5 Base address:0x6500
When the system boots the driver is loaded and the 905B is recognized by
the driver.
eth0: 3Com 3c905B Cyclone 100baseTx at 0x6500, 00:10:5a:11:13:5f, IRQ 5
8K byte-wide RAM 5:3 Rx:Tx split, Autonegotiate interface.
Media override to transceiver type 0 (10baseT).
Enabling bus-master transmits and whole-frame receives.
I've tried increasing the debug level on the driver and still get no
real information. debug=4 reveals when the driver is loaded:
olive kernel: 3c59x.c:v0.99H 11/17/98 Donald Becker http://cesdis.gsfc.nasa.gov/linux/drivers/vortex.html
olive kernel: eth0: 3Com 3c905B Cyclone 100baseTx at 0x6500, 00:10:5a:11:13:5f, IRQ 5
olive kernel: Internal config register is 800000, transceivers 0xa.

olive kernel: MII transceiver found at address 24, status 786d.
olive kernel: MII transceiver found at address 0, status 786d
olive kernel: Enabling bus-master transmits and whole-frame receives.
When I start the network with '/sbin/init.d/network start' I see:
olive kernel: eth0: Initial media type Autonegotiate.
olive kernel: eth0: MII #24 status 786d, link partner capability 0020, setting half-duplex.
olive kernel: eth0: vortex_open() InternalConfig 00800000.
olive kernel: eth0: vortex_open() irq 5 media status 8080.
olive kernel: eth0: Filling in the Rx ring.
olive kernel: eth0: Media selection timer tick happened, Autonegotiate.
olive kernel: eth0: MII transceiver has status 7869.
olive kernel: eth0: Media selection timer finished, Autonegotiate.
I've tried getting information from the vortex-diag program as well.
vortex-diag -a gives:
vortex-diag.c:v1.05 5/22/98 Donald Becker (becker@cesdis.gsfc.nasa.gov)
Found a 3Com PCI Ethernet 3c905b rev 0 at 0x6500.
No interrupt sources are pending.
Transceiver/media interfaces available: 100baseTx 10baseT.

vortex-diag -e gives:

Found a 3Com PCI Ethernet 3c905b rev 0 at 0x6500.
