Not quite true - it seems to be more closely related to your libc6 
version. I know that in Debian the 2Gb limit magically went away on 
ext2/ext3 (possibly even on kernel 2.2 IIRC) when libc6 was updated at 
some point during development this year (before woody, the current 
stable, was released). I would have thought MDK8.2 would be recent 
enough to support >2Gb files...

See if you can create a >2Gb file on the local machine to test one way 
or the other; assuming you have shell access, try something like

dd if=/dev/zero of=/tmp/test.dat bs=1k count=3000000

This should create a 3Gb file on the local disk (assuming you have 
enough disk space on that partition, of course :)
