Outputs attached:
  x1300-vga - rhd_conntest -s 1:0.0 (VGA cable attached.)
  x1300-dvi - rhd_conntest -s 1:0.0 (DVI cable attached.)
  7146.174B.0920.vga.rom - rhd_conntest -d 1:0.0

When I used the VGA cable, I wasn't getting a picture on the screen.  I 
just swapped the cables while X was running, so I suppose that just 
means that the driver/card was already initialized to use the DVI 
output.  If I understand the results correctly, it does appear that it 
was detecting the monitor, even though I wasn't getting a signal.  Let 
me know if you need me to do anything differently.

I suspected that was the case, but I wanted to mention it anyway, as 
this wouldn't be the first time I spent hours trying to nail down a 
hardware issue only to discover that the problem was caused by a KVM all 
along.
