Don't know what version is being discussed, but the 2.2.x are capable
of 2G swap partitions. From mkswap man page:
The old setup wastes most of this bitmap page, because zero bits
denote bad blocks or blocks past the end of the swap space, and a
simple integer suffices to indicate the size of the swap space,
while the bad blocks, if any, can simply be listed. Nobody wants
to use a swap space with hundreds of bad blocks. (I would not even
use a swap space with 1 bad block.) In the new style swap area
this is precisely what is done. The maximum useful size of a swap
area now depends on the architecture. It is roughly 2GB on i386,
PPC, m68k, ARM, 1GB on sparc, 512MB on mips, 128GB on alpha and 3TB
on sparc64.
