I'm not sure this is true - i think that this limit was there but was
removed in newer versions of ext2/3

I have created larger filesystems on 64-bit.

More or less true, but some newer hardware and device drivers 
have fixed this.  The keyword you need to look for is "64-bit LBA".

I've had success with an Atto celerity fibre channel adapter and
an infortrend-based RAID on x86_64.  However, each one needed a
firmware/driver update from what was shipped to me in December of
last year to work.
