How to mount a Mitsubishi MELCARD (PCMCIA SRAM)?


Okay, I've researched this pretty extensively. I want to read (and possibly write to) a Mitsubishi MELCARD MF31M1-LCDAT01 on an old Toshiba Satellite 4030CDT laptop.

I tried Google first and got this (among a lot of other things, but this was the most promissing thing I found, apart from descriptions of similar problems, even on old Win systems):

http://kogs-www.informatik.uni-hambu.../msg00307.html

However, my system - running Debian Etch 4.0r2, uname says:
Code:
$ uname -a
Linux hostname 2.6.18-6-686 #1 SMP Wed Jan 23 03:23:22 UTC 2008 i686 GNU/Linux
- simply doesn't behave as described: I don't get any new device node in /dev I could mount in any way.

I tried cardmgr:
Code:
# cardmgr -o
cardmgr[5900]: could not adjust resource: IO ports 0x100-0x3af: Function not implemented
cardmgr[5900]: could not adjust resource: IO ports 0x3e0-0x4ff: Function not implemented
cardmgr[5900]: could not adjust resource: IO ports 0x820-0x8ff: Function not implemented
cardmgr[5900]: could not adjust resource: IO ports 0xc00-0xcf7: Function not implemented
cardmgr[5900]: could not adjust resource: memory 0xc0000-0xfffff: Function not implemented
cardmgr[5900]: could not adjust resource: memory 0xa0000000-0xa0ffffff: Function not implemented
cardmgr[5900]: could not adjust resource: memory 0x60000000-0x60ffffff: Function not implemented
cardmgr[5900]: could not adjust resource: IO ports 0xa00-0xaff: Function not implemented
cardctl says:
Code:
# cardctl ident
Socket 0:
  product info: "NETGEAR MA401 Wireless PC", "Card", "Version 01.00", ""
  manfid: 0x0156, 0x0002
  function: 6 (network)
Socket 1:
  no product info available
This all looks pretty bleak to me - does anyone have any idea if this is doable at all? The last system I'm sure this was working on was Win98, so I really don't want to try and go back this far...

Another option: Could anyone confirm that it should be possible to mount this type of card on an old Sarge system using a 2.4 kernel? I could get my hands on a PCI based internal PCMCIA reader that I could put into an old box still running Sarge, but I'd rather not spend the money if success is improbable.

Third solution: I can read the card using a 1992(?) Zeos Pocket PC running MSDOS 5.0. The thing can communicate using interlnk/intersrv, two old DOS tools to hook up two computers via parallel ports. Is there any tool available to communicate with an intersrv instance from GNU/Linux? Remember, as long as I can't read that card, I can't put anything new on the Zeos. And what I read about using interlnk with FreeDOS doesn't sound too encouraging. Finally, I also read something about a DOS version of a tool named PLIP which is available for GNU/Linux and DOS, but as I said, I can't install anything on the old device... dead end?

M.
