I don't think it is worth it to use pnp under LEAF. Disable pnp in the
card setup.

Which you don't identify here. IRQs are a constrained resource. I don't
remember if you have access to IRQ8-15 for 509B NICs, but even if you do,
be sure you don't have an interrupt conflict.
If you disable the serial ports, you get IRQ3 and IRQ4. You can usually
use IRQ5 and IRQ7 as well, since parallel ports don't usually need
interrupts.

I have never used more than two 3c509s at once, and I found that letting
the automatic discovery work was the most reliable method (no "io=" and
especially no "irq=" when loading the modules). You might try
just io (i.e. io=0x300,0x310,0x320,0x330) if the autodetection doesn't
work.

wd and ne are common. Look at the main chip part numbers, and google
them.

I haven't. However, Charles seems to have good luck with the D-Link 570TX
(tulip driver, pci bus). I would expect most ISA cards to be tricky with
so many in one box.
