"Out of range" starting Xorg on dual display

[Pat Maddox]

I've got a dual display setup, and it had been working fine once I
finally got the config done.  They're two displays running off one
graphics card, one through the DVI output and one through the D-SUB. 
Today I had to switch the inputs that the monitors use, and it just
doesn't work anymore.  I get a message on my left display that says
"Out of range."  This isn't an Xorg or FreeBSD error, it's a message
from the displays built-in HUD.  This doesn't make any sense because
as far as Xorg is concerned, there shouldn't be any difference.  The
D-SUB display should be on the left, and the DVI one should be on the
right.  I really don't understand what could be causing a problem, but
for what it's worth, the display now connected to the D-SUB has always
been more finicky than my other display.  They're a ViewSonic vp201
(D-SUB) and Dell 2001fp (DVI).  Here's my config:
