3c509.c / Multiple cards problem

Hi -
I am having trouble with the Linux kernel 3COM 3c509 driver, version 2.2.16.
I have two (ISA) 3C509B cards, and I cannot make them work. This is the output
I get from loading the driver:

#
eth0: 3c509 at 0x300 tag 1, 10baseT port, address 00 01 02 46 fa cc, IRQ 10.
3c509.c:1.16 (2.2) 2/3/98 becker@cesdis.gsfc.nasa.gov.
eth1: 3c509 at 0x300 tag 2, 10baseT port, address 00 50 04 89 82 b4, IRQ 10.
3c509.c:1.16 (2.2) 2/3/98 becker@cesdis.gsfc.nasa.gov.

This is /proc/ioports before i try
#
0000-001f : dma1
0020-003f : pic1
0040-005f : timer
0060-006f : keyboard
0070-007f : rtc
0080-008f : dma page reg
00a0-00bf : pic2
00c0-00df : dma2
00f0-00ff : fpu
01f0-01f7 : ide0
03bc-03be : parport0
03c0-03df : vga+
03e8-03ef : serial(auto)
03f6-03f6 : ide0
03f8-03ff : serial(auto)
2000-2007 : ide0
2008-200f : ide1

and /proc/interrupts
#
           CPU0
  0: 1156083 XT-PIC timer
  1: 22456 XT-PIC keyboard
  2: 0 XT-PIC cascade
  7: 1069 XT-PIC parport0
  8: 1 XT-PIC rtc
 12: 666 XT-PIC PS/2 Mouse
 13: 0 XT-PIC fpu
 14: 108629 XT-PIC ide0
NMI: 0

I think the problem is that the cards are being allocated the same IRQ and IO.
In Documentation/networking/net-modules.txt it states...

3c509.c:
        io = 0
        irq = 0
        ( Module load-time probing Works reliably only on EISA, ISA ID-PROBE
          IS NOT RELIABLE! Compile this driver statically into kernel for
          now, if you need it auto-probing on an ISA-bus machine. )

So I tried to pass parameters to the module, like so:
modprobe 3c509 io=0x300,0x310 irq=10,11
modprobe 3c509 io=0x300 io=0x310 irq=10 irq=11

...but no dice: the module complains of 'unknown parameter io='.

Reading through the source, it appears that 3 parameters are recognsed - io,
xcvr and debug although I can't figure out what the last two do.

So... is it possible for me to use two of these (rather nice) cards at once,
or is this a WIP? Do I need to link 3c509.c statically?

Thanks for your time!
