User space needs to be 64 bit clean - which translates to an installation
which has the 'LFS' patches installed. This applies to most modern
distributions now I think. An d to be honest, ext2 will give you 2G+ files
in 2.4 as well.

Done by the above.

I know we have it up on an ia64 box somewhere and it is functioning,
exactly what hoops had to be jumped through to get it built I do not
know, but I do not believe xfs itself needed changing. You may need
other kernel changes for your flavor if ia64 of course.
