Some of Hatsuhiro's question may arise from an old Linux
reference. Old kernels (pre 2.2.x I believe) allowed a maximum
of 128MB per swap partition, and so multiple swap partitions
was a workaround for that limitation.  Any modern kernel has
raised the limit (to 2GB on the x86 architecture for example).

There may be performance advantages to having multiple swap
partitions spread across different spindles, but not when
we are talking about chopping up a single drive.
