This question has been asked before (in the FAQ ?).
It goes something like this (haven't tried it, can't remember all of it).
From dos/windows set up the swap partition and leave.
From Linux gzip the partition. (I think like dd if=/dev/disk37 | gzip file)
Then you can include mkswap,swapon in a file run at boottime.
When you wan't to use windows just swapoff, gunzip, reboot.
This comes with NO WARRANTY , it's the best I can do for yo all.
