I used the blob long, long ago. I THINK that it (unlike nv) used something like
aspect.  I remember liking the nv driver better because every mode was
fullscreen.

If I try to do a screen shot, it shows up just fine, so it seems like it is
definitely a display problem.  I'll take a picture with my digital camera.

Yes.  "Scaling resolution on a widescreen panel" is present in both of the
broken modes (1152x864, 1024x768). I did notice something that I missed before.
One of the modes is clipped on the bottom. (And it says: Scaling resolution on
a portrait panel)

(BTW.  The panel is natively 1680x1050, but I left that resolution of all of
the tests.)

Here's my exhaustive test results:

                 Result              Scaling_String
   1360x768      Clipped on Bottom   "Scaling resolution on a portrait panel"   
   1280x800      Works               None
   1152x864      Corrupt             "Scaling resolution on a widescreen panel"
   1280x768      Works               None  
   1280x720      Clipped on Bottom   "Scaling resolution on a portrait panel"
   1024x768      Corrupt             "Scaling resolution on a widescreen panel" 
   800x600       Clipped on Right    "Scaling resolution on a widescreen panel"
                  (~100 pixels)
   640x480       Clipped on Right    "Scaling resolution on a widescreen panel"
                  (~100 pixels)
