In case that doesn't work...couldn't you possibly write a small C or Perl
program that read the first file a byte at a time, and writes to a file a
byte at a time - starting at a given offset in the file and until you reach
1G from the offset? 

I would think there'd be something out there that did this, however...can dd
do this?
