what is the Maximum Swap partition size and useful size ???

[ha haha]

Greeting,

 I'm using FC4 with 2.6 kernel on i386 and x86_64
arches now, Just wonder whether the maximum swap size
changed. The makeswap manual seems too old (although
not true) if look just from it timestamp.

...
SEE ALSO
       fdisk(8), swapon(8)

Linux 2.2.4                      25 March 1999        
              MKSWAP(8)
...

I've tried to create 4GB, 8GB, 16GB, and 32GB swap
partitions, all mounts well, but I don't know whether
all of them are theoretically be full in use -- not
only the first 2GB are usable. 

Please crarify. Many Many Thanks.
