...but it did find it! smartd is light-weight in its resource use, at
least I've never noticed any slow-downs I could blame on it, so IMO
installing and enabling it on all Linux boxes is a no-brainer. I have it
set up to generate and mail me reports on a weekly basis.

Shouldn't that be:
 
   fsck -l bad-blocks /dev/mapper/vg_computer-lv_root

I think your shell redirection would clear the badblocks list in
preparation for writing to it, so you'd empty the file before fsck could
apply it.

If I am making a mistake, or there is a better way to do this, then I
would greatly appreciate any advise.

I might have run fsck with the -c option, which gets passed through to
e2fsck. This combines both operations - it runs badblocks internally,
applies anything it finds to the badblocks list and then (presumably)
checks the filing structure.
