Hello Jan, thank you for your help. 

I have compiled this source code: the output is presented below

          TYPE  SIZEOF ALIGNOF
          char       1       1
         short       2       2
           int       4       4
          long       4       4
     long long       8       4
         float       4       4
        double       8       4
   long double       8       4
        void *       4       4
void (*)(void)       4       4
      intptr_t       4       4
        size_t       4       4
       wchar_t       4       4
         off_t       4       4

      uint32_t       4       4
      uint64_t       8       4
    struct x16       4       4
    struct x32       8       4
    struct x64      16       4
        mode_t       4       4
        time_t       4       4

struct sockaddr_storage     128       4


Also I have tried to recompile needed kernel modules for iptables work:
net/netfilter/x_tables.ko, net/ipv4/netfilter/ip_tables.ko and
net/ipv4/netfilter/iptable_filter.ko  but without any positive result. 

I have tried to enable debugging for this modules and rebuild kernel included
those modules in it, not as single modules - but also without result.

I have check ABI flags for all binaries (modules and iptables), as was
described here http://wiki.debian.org/ArmEabiPort - result presented below:

home/aidjek/iptables-1.4.12/build/bin/sbin# readelf -h iptables | grep Flags 
  Flags:                             0x202, has entry point, GNU EABI, software
FP

readelf -h /home/aidjek/iptables-1.4.3.2/build/bin/sbin/iptables | grep Flags 
  Flags:                             0x202, has entry point, GNU EABI, software
FP

readelf -h net/ipv4/netfilter/ip_tables.ko | grep Flag
  Flags:                             0x200, GNU EABI, software FP

readelf -h net/ipv4/netfilter/ip_tables.ko | grep Flag
  Flags:                             0x200, GNU EABI, software FP


Also tried to recompile kernel modules from original source code and have found
another errors in dmesg: 
[442992.546875] translate_table: size 632
[442992.570312] Finished chain 1
[442992.578125] Finished chain 2
[442992.585937] Finished chain 3
[442992.593750] ip_tables:  target: invalid size 12 != 8

But I think it's incompatibility of modules version or anything else, because
module iptable_filter.ko - cannot load in this situation.

Also I am discussing this issue on different  russian significant linux
communities and will let you know - if anything will be usefully for this
issue.

Also I have make one more strace outputs : http://pastebin.com/DvxVcUiT 
one of it - it's execute command "iptables -L" , another  "iptables --version"

Please let me know if you need further assistance or info.

Thank you in advance, Evgheni.
