Do you see in the dmesg output that both cards are using irq 10?
You must change one of them.  They cannot both be used with the
same interrupt.  For the ne1 you should be able to download a
DOS utility to change the interrupt (irq 10) setting and even
the port (0x300-0x31f) setting if you wish.  Often there is an
EEPROM (or some kind of non-volatile storage) on the card which will
save the settings while the computer is off.  I would just change
the irq 10 setting on that card to another number.  You might try
irq 5 if you don't have a COM3 (internal modem, for instance) or
irq 7 if you don't use the parallel port.  Sound cards will often
use irq5 or irq 7 by default, though, so if you have one of those,
you might want to check which interrupt it's using.  You might be
able to use irq 2 for the ne1 if you don't have an ATX power supply.
ATX power supplies use irq 9, which is wired to irq 2, in a way.
My NE2000-compatible card also allows choosing either irq 11 or irq
12.  You could try using the DOS utility on one of these driver
disks:
