The format could be(*) the same, but a few issues in the e.g. page cache, and API/ABI prevent current 32-bit linux systems to exceed 2GB file size.
For further reading, see my patches for this at: ftp://mea.tmt.tele.fi/linux/LFS/

(*) The format is basically the same, however EXT2 code isn't currently quite clean to handle large file sizes at 32-bit machines. In theory it is just a matter of using 'long long' variables, but it isn't quite that simple...
