I haven't been able to find any.

I think TVA is a big part of the problem.  They are recognized as the 
official source for map data in the areas they serve, not the USGS.

You can download tiffs from the TVA online "store", but they are not 
standard geotiffs that xastir can read.  It may be possible to just 
convert thee to standard bitmaps and register 4 corners, but I did not 
try this.  I seem to recall problems being related to a state 
projection? Note the download option at the TVA onine map store looks 
like you're going to be charged for the maps, but you actually get them 
for free if you keep working your way through the process.  (This TVA 
info is a year or so old.)

The USGS DLG/SDTS contour data is very incomplete for TN, probably due 
to the TVA vs USGS thing.

The short answer is: I couldn't find any, and I would be interested in 
anything you found.
