Although I haven't had to deal with it using later kernels, I
resolved this problem some years ago by resetting the i/o base
address on each nic. ie 0x310 0x320 0x330 etc. I then added an
'ether' command for each at boot time. ie ether = 5, 0x310, 12,
0x3c509, eth0 - where these correspond to the desired irq, base i/o
address, transciever type, address conflict flag and interface.
I know networking has been upgraded since, and I'm not sure if this
would still work, and on tulip cards, but I'd be interested to know.
Something else to try, hope it helps,
