Documetation? Is this a trick question? It's Linux, of course there is
no current documentation except for the source ;)

/me ducks and runs ;)

Not on 2.6 kernels, no.

[sparrow:joe] $ cat /proc/swaps
Filename Type Size Used Priority
/dev/mapper/vg0-swap partition 8388600 0 -1

I use 4-8 G swap areas on 32-bit x86 and 64-bit amd64 kernels.

You probably need a new version of mkswap if it insists that 2G is the
maximum - it sure isn't a kernel limitation anymore.
