I went through this a couple of months ago.  Here's what I found:

I ran tests on both SLES7 with Reiser, and SLES8 with EXT3.  I was able to create 
files larger than 2 gb. on both, with one caveat mentioned below.

SLES7/Reiser

-rw-r--r--    1 root     root     3974090752 May 27 13:12 bigfile1

SLES8/EXT3 (formatted with -T largefile4)

-rw-r--r--    1 root     root     5100758784 May 27 13:01 bigfile

The caveat is that with EXT2 or EXT3, you have to specify "-T largefile4" or the 
filesystem is created with 1k/inode.  "largefile4" creates 4MB/inode, which wastes 
considerable space on small files,
but allows files much larger than 2 gb.

There's one more gotcha:  Some old packages compiled against old versions of the 
libraries (libc5 and glibc 2.1) may either not have the 64-bit file handling API's, or 
may have broken ones.  The
packages I looked at on both SLES7 and SLES8 appear to be current, but I can't vouch 
for vendor products.

One particular problem was the version of ssh that ships with SLES7.  Scp has the 
large-file-support deliberately disabled because of problems with other (non-Linux) 
operating systems.  The version
shipped with SLES8 fixes this, and WILL compile under SLES7, but the RPM won't rebuild 
there without major surgery, due to other issues.
