This is really more a Server-Linux question rather than a Netatalk question,
but in any case...
Linux (at least I know fer sure RH does) has a 128MB swap partition size, so
using 256MB of swap space would require you make two separate partitions of
128MB each. How much swap your machine uses, of course, will completely
depend on the usage pattern for your particular site. If it helps, I have a
file server doing Samba, Netatalk, and printing for about 250 users, 256MB
RAM, 128MB partition for swap, and it NEVER uses it's swap space (ok, ok, it
did use 300K of swap once). If you plan on running X on these servers, that
will use lots more RAM.
A better way to guage your needs is to go to an existing server (assuming
its linux), and run vmstat (see the man pages on vmstat for explanation) at
the busiest time of the day and work from there.
