513M of swap.

A)  Disk is cheap.
B)  The day you start hitting swap, you'll double
    your RAM to 256M, so at that point in time
    your swap will be 2x RAM, which is generally
    a good rule.
C)  The day you start hitting swap with the 256M
    configuration, you'll double your RAM to
    512M, so at that point in time your swap
    will be RAM + 1M.
D)  DISK IS CHEAP.

So in conclusion, 1025M of swap for 128M of RAM.

HTH,
