total memory = 256 MB
avail memory = 239 MB

So that works well with the vmstat -s numbers.  However, that still
doesn't really explain where that memory is.

I guess top should be patched or something to reflect the vmstat -s
numbers instead of whatever it's currently using.

Would you mind looking at vmstat -s and see if you're missing 48MB?

vmstat -s|awk '{ print $1*4096, $0 }'  is handy.  (assuming your first
row looks like this      4096 bytes per page)
