Apparently the V1100 doesn't have an edid, so we don't know what modes it
supports.  you can add add the sync ranges, etc. to a monitor section
associated with the output.

On the primary dac we are able to use load detection to see if a monitor is
attached.  In this case, we find one, but since it has no edid, the server just
added the default sync ranges and modes.

This doesn't seem right.  The log clearly shows an edid on the monitor on the
dvi port initially.  later in the log it disappears.  are you sure you didn't
disconnect the monitor on the dvi port at some point?
