I think my idea was crazy;) because with the command I changed the table with 
the exports:
from:
objdump -x fcpci-lib.o.org | tail
00004c20 R_386_32          .rodata
00004c24 R_386_32          .rodata
00004c28 R_386_32          .rodata
00004c2c R_386_32          .rodata
00004c30 R_386_32          .rodata
00004c34 R_386_32          .rodata
00004c38 R_386_32          .rodata.str1.1
00004c3c R_386_32          .rodata.str1.1
to:
objdump -x lib/fcpci-lib.o | tail
0000000000004c20 R_X86_64_32       .rodata
0000000000004c24 R_X86_64_32       .rodata
0000000000004c28 R_X86_64_32       .rodata
0000000000004c2c R_X86_64_32       .rodata
0000000000004c30 R_X86_64_32       .rodata
0000000000004c34 R_X86_64_32       .rodata
0000000000004c38 R_X86_64_32       .rodata.str1.1
0000000000004c3c R_X86_64_32       .rodata.str1.1

but, I guess, the executed code stays 32-bit and the access to the memory 
wasn't changed to 64-bit access.

I guess the pointers are now 64-bit long and don't fit in the places in the 
32-bit executing code where before the converting were the 32-bit pointers.

Is anywhere how-to for adapting the 32-bit code to 64-bit? Or anything 
regarding the theme?

Thanks for the answer.

BTW: I've got the answer from AVM, that the driver for my card will be 
available in the Q3 2005.
