In my slack 8.1 system I have this for the mkswap manpage:
MKSWAP(8) Linux Programmer's Manual MKSWAP(8)
NAME
mkswap - set up a Linux swap area
SYNOPSIS
mkswap [-c] [-vN] [-f] [-p PSZ] device [size]
DESCRIPTION
mkswap sets up a Linux swap area on a device or in a file.
...
Presently, Linux allows 8 swap areas. The areas in use can
be seen in the file /proc/swaps (since 2.1.25).
Presently, Linux allows 8 swap areas. The areas in use can
be seen in the file /proc/swaps (since 2.1.25).
mkswap refuses areas smaller than 10 pages.
If you don't know the page size that your machine uses,
you may be able to look it up with "cat /proc/cpuinfo" (or
you may not - the contents of this file depend on archi-
tecture and kernel version).
my cpuinfo didnt seem to have anything pertinant to page size, however others
might... cpuinfo seems a lot less relevent than meminfo... Why would
cpuinfo be included, but not meminfo?

:
: I don't believe the swap format issue has been of any importance since the
: transition from Kernel 2.0 to 2.2. As long as your swap partition was
: formatted under a 2.2 or later kernel, it should be in the new format.
: (Unless you said "mkswap -v0", but there's no reason to do that, unless
: you have some need to make a swap space that's backwards-compatible with
: old kernels.)
:
: If you really need to know for sure which kind of swap space you have, type
: this (you'll need to be root):
:
: dd if=/dev/hdXX bs=4096 count=1 | strings
:
: where "/dev/hdXX" is your swap partition. If you see "SWAP_SPACE" in the
: output, you have an old-style swap partition. "SWAPSPACE2" indicates the
: new style. (If you don't see either of the above, try increasing the "bs="
: number to higher powers of 2...the power that first reveals the swap
: space signature is equal to your page size in bytes.)
