Poor documentation of kernel parameters

How do I say kernel this:

I have two ISA network cards,
ne2000 IRQ 10 IO 0x300-0x31f DMA none
WD8003-old IRQ 5 IO 0x380-0x39f DMA none

using kernel parameters?

Why in the doc for kernel parameters in Documentation/kernel-parameters.txt
is written:
ether= [HW,NET] Ethernet cards parameters (iomem,irq,dev_name).and in net/ethernet/eth.c in function eth_setup
__initfunc(void eth_setup(char *str, int *ints))
{
struct device *d = dev_base;

if (!str || !*str)
return;
while (d)
{
if (!strcmp(str,d->name))
{
if (ints[0] > 0)
d->irq=ints[1];
if (ints[0] > 1)
d->base_addr=ints[2];
if (ints[0] > 2)
d->mem_start=ints[3];
if (ints[0] > 3)
d->mem_end=ints[4];
break;
}
d=d->next;
}
}

It looks like the ether= has format of ether=baseaddr,mem_start,mem_end,
which is in direct contradiction with the documentation.

What means the iomem in the documentation? Is it some kind of
hybrid between I/O port and memory address?
What means dev_name in ether? Should I write there

a) NE2000
b) ne2000
c) DP8390
d) dp8390
e) 8390
f) ne
g) NE
h) DP-8390
i) dp-8390
j) ne-2000
k) NE-2000

for ne2000

and
a) WD
b) wd
c) wd8003-old
d) WD8003-old
e) wd8003
f) WD8003
g) wd-old
h) wd-OLD
i) WD-old
j) WD-OLD
k) wd-8003
l) WD-8003

for wd8003-old?

Why isn't in the doc for kernel parameters written syntax of the kernel
parameters? Should they be separated by colon, semicolon, space, tab,
whitespace, newline?
