No, but :
It was discussed a bit in, I think, the Console-tools thread.
256 MB was often recommended, but I think more from a general Linux rule of thumb.
Mine is 256 MB, and after checking it in Load-applet now and then I believe half would have been quite enough.
But then I'm not a heavy user.


EDIT.
I had one bad experience with swap at my first tries.
Seeing a swap part. (made with "pb"-cfdisk) not recognized, I changed it to something else, and then back to swap.
Then nothing worked properly until I had reformatted my card.
( Of course, knowing no Linux I didn't know how to properly solve it.)
