You can crank up datasize to be larger than RAM assuming that you have
sufficient swap configured.  It'll just be slow as fsck starts paging.
At some point on 32-bit architectures like the i386 you'll run into the
address space limit, probably at 2-3GB.

I think julian_at_ has mentioned having a version of fsck that uses
external storage.  I would expect a substantial speed impact, and you
would need at least one other file system mounted rw.
