It looks like you have a somewhat large file system, apparently with a
lot of small files on it.  The message indicates that you need to be
able to allocate over 3GB of address space to handle this.  As such you
will need a 64-bit machine, ideally with 4GB or more RAM and probably
with a large swap partition.

In theory it should be possible to write a constrained memory use version of
fsck, but to my knowledge no one has done so and I suspect it would be a
time consuming development effort.
