Ok, thanks to Warren and Steve for the tips!

Turns out that my swap failed to work.  I thought that when I
did a mkswap, a label would be used and the fstab would somehow
get correctly set.  I was wrong on both counts. grrr.

I had to hardpath the swap (/dev/hda3) into the fstab and
then run swapon -a command.  I rechecked swap and now I have
something other than "0"

Again, thanks for the tips!
