2.5 includes the changes for 2G support in smbfs. You need to be aware
that it may crash, burn and/or eat your files. But if that does not scare
you then please test it.

The negotiation patch was sent for the 2.2 samba CVS tree, but I don't
know if it is in yet. 2.2.5 still needs the patch (don't know about
2.2.5-1, because that is an rpm and is not necessarily the same as the
2.2.5 source).

Lot's of people never use files larger than 2G. Requests for supporting it
in smbfs is fairly new. Going back further the kernel interfaces didn't
even allow 2G files on 32bit hardware (lseek, read, write). I think it was
with kernel 2.2 and glibc 2.2 that support for it started to be common.
