It looks like 28MB free to me. Or are you saying this happened at some
other time?

As long as there is a lot of memory used by 'cached' and 'buff', there
isn't much need to swap. If you had 100% used, 0% cached, and 0%
swapped, that would be weird. Your situation doesn't seem weird though.
There are lots of ways to alloc a lot of memory to see if your swap
works. Today I found out that diff is a huge memory hog. Try
diff -ua /dev/hda /dev/hdb
And let me know if it swaps :)
