On the x86 architecture, your swap partition size is limited to 128 MB.
You can, however, have multiple swap partitions. There is absolutely no
point in makign a swap partition of more than 128 MB, as everything after
the first 128 MB will be wasted.
If you REALLY need that much swap, you need to make several swap
partitions, each 128 MB big. However, unless you are running a
ridiculously fast disk array, having 128 MB of swap fill up will make
things so slow that your system will become completely unuseable.
