In looking at the dmesg log for bug 3440, it looks like eth0 is a
RealTek adapter and eth1 is an eepro100.

"8139too Fast Ethernet driver 0.9.27
eth0: RealTek RTL8139 at 0xd0842000, 00:50:fc:4c:d6:9b, IRQ 9
eth0:  Identified 8139 chip type 'RTL-8139C'"

"eepro100.c:v1.09j-t 9/29/99 Donald Becker
http://www.scyld.com/network/eepro100.html
eepro100.c: $Revision: 1.36 $ 2000/11/17 Modified by Andrey V. Savochkin
<saw@saw.sw.com.sg> and others
eth1: 0000:00:0e.0, 00:A0:C9:43:8C:E4, IRQ 15."

Another way to verify which driver is associated with a device name is
to use 'ethtool -i eth0'.  This will report the driver name and version
of the driver.

If the same problems happens with the pcnet32 driver, I can help you
debug the problem with the pcnet32.
