I've come to conclude that this is not a problem.  It seems the radeon driver
disables the LVDS display (the local laptop screen) when it detects the DVI
display plugged in.  What was tripping me up was that I didn't realize this as
the DVI display does not work due to

http://bugs.freedesktop.org/show_bug.cgi?id=18564

If I go ahead and log in blind, start up a terminal, and do a "xrandr --output
LVDS --auto" the local laptop display comes up fine (and, from the xrandr
report, I also see that the radeon driver believes it has turned the DVI
display on).

I'll close this bug report.

Cheers!  -Tyson

PS:  Actually, if I use the version prior to commit d744dc01... (i.e., the one
I thought was working when I submitted this report) and check xrandr after
logging in, I see that driver actually thinks that it has disabled the LVDS
display despite the fact that it hasn't.
