The seek offset has nothing to do with the real offset, although since the addition of the disklabel values is done in an unsigned long instead of an off_t ("long long" or "quad_t"), I believe you *will* see a 4G limit without further kernel work. Are you sure you meant "partition"? Eventually, someone will need to be lent a 9G disk to get the off_t changes propagated where they need to be...
