After completing the fix listed at http://www.thinkwiki.org/wiki/Installing_Ubuntu_7.04_on_a_ThinkPad_T43#Swap_and_Hibernation_problem, which is essentially the same as what's listed above, hibernation is working fine for me, and swap is enabled on boot, however swapon -s is listing an entry for both /dev/sda2 and /dev/mapper/sda2, and free -m shows double the amount swap space that it should.
This seems like something to me like something to be concerned about, but I'd like to get the opinion of someone more with a more thorough understanding of these issues.

Note that this is mentioned above (https:/ /launchpad. net/ubuntu/ +bug/66637/ comments/ 30) by Crakie, but no one commented on the appearance of double the swap size.
