Well... Originally (before sending you this prog) the latest entry was
        {
                .name = "CPU1CST ",
                .address = 0x40fdd50,
                .len = 100
        },
in order to chekc it worked.

I've taken care that 0x040fd800 is correctly somewhere at the ACPI table:

ducrot@poup$ cat /proc/iomem 
00000000-0009f7ff : System RAM
0009f800-0009ffff : reserved
000a0000-000bffff : Video RAM area

000e0000-000effff : Extension ROM
000f0000-000fffff : System ROM

  002aa885-0035bebf : Kernel data
040fd800-040ff7ff : ACPI Tables
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
     Here...

040ff800-040ffbff : ACPI Non-volatile Storage
040ffc00-0fffffff : System RAM
f4000000-f400007f : 0000:00:0e.0

fc000000-fdffffff : PCI Bus #01
  fc000000-fdffffff : 0000:01:00.0
fff80000-ffffffff : reserved

and this worked:

can't decode CPU0IST 
CPU1IST  3ffefb60 87
can't decode CPU1IST 
CPU0CST  3ffef988 1d8

040fddb0: 42 5f 50 43 

so I must admit I'm puzzled.

BTW, its not related, but there is 1Go ram.  You should enable highmem in
order to get an extra 128Mo.
