"this device cannot be used for FTL" with a SMART PCMCIA linear flash

[Miernik]

I'm trying to get a "SMART Modular Technologies 4MB FAST FLASH CARD 
SM9FA2043IP280" PCMCIA linear flash Intel Series 2+ card working.

The explanation of SM9FA2043IP280:

SM      Smart Modular
9       Product Category:       Memory Card
F       Technology:             Flash
A       Attribute:              With Attribute (2kB)
2       Nop. of banks:          2 Bank

80      Card Speed:             80ns


FLA16MPX16ICB REV.A

To know what I'm working with, I have opened the card, and found these 
4 chips:

2 * chip:
---------
Intel

E28F016SA
70   5.0V
120  3.3V
U84433T1C
1993

Flash
---------

---------
ATMEL
AT28C16
15TC
9837
---------

---------
IDT 74FCT
108CTQ
KP84ST
---------

I have accidentally erased attribute memory of this card, so it is 
detected only as anonymous memory. I fix it like this:

card "Anonymous Memory"
  anonymous
  cis "cis/smartm-4mb-flash.dat"
  bind "memory_cs", "ftl_cs"


I am using 2.4.22-3 kernel from Debian, self-compiled, not compiling 
pcmcia-modules from the kernel, but separately. 
I compiled pcmcia-modules_3.2.2-1.4.

These are self-made packages of my kernel and pcmcia-modules:
http://www.miernik.ctnet.pl/debian/pool/kernel-image-2.4.22_tarnica.1.0_i386.deb
http://www.miernik.ctnet.pl/debian/pool/pcmcia-modules-2.4.22_3.2.2-1.4+tarnica.1.0_i386.deb

This is my problem:

tarnica:~# ftl_format -i /dev/mem0c0c
this device cannot be used for FTL!
format failed.
tarnica:~#

tarnica:~# ftl_check /dev/mem0c0c
Memory region info:
  Card offset = 0x0, region size = 4 mb, access speed = 200 ns
  Erase block size = 1 bytes, partition multiple = 1 bytes

No valid erase unit headers!
tarnica:~#

If I try a dd to it I get "input/output error" or no error messages, 
but when I try to dd it back ftom the card, I get a file with all bits 
set to 1. Depending on if I try to use /dev/mem0c, /dev/mem0c0b or 
/dev/mem0c0c.

I forgot to note exactly what when happens with dd, and I can't check 
it not, as I have my WLAN card in that PCMCIA slot to access the 
Internet, I can check it later if needed.

Logs, pcmcia configuration, and other detailed info of my problems can 
be found in: http://www.miernik.ctnet.pl/mtd/3-repeat-clear/
