That's absurd. I'm using a 32 bit processor and I have files of 9 gigas, 
so having large files is not an intrinsic processor limitation.

Actually, if you look at the opensuse manual, «Table 17.2. Maximum Sizes 
of File Systems (On-Disk Format)» 
<http://localhost/usr/share/doc/manual/opensuse-manual_en/manual/sec.filesystems.lfs.html#tab.maxsize>
 
shows the large file support limits for NFS:

    File System       File Size (Bytes)    File System Size (Bytes)
- --------------------+-------------------+----------------------------
NFSv2 (client side)     2^31 (2 GiB)         2^63 (8 EiB)
NFSv3 (client side)     2^63 (8 EiB)         2^63 (8 EiB)


The kernel limit for 32 bit processors is  2TiB (2^41 bytes).


So, 4GiB is very far from the limit. Either there is some parameter needed 
somewhere, or there is a bug.
