If I may provide a fresh perspective;  the emails I read from this thread 
seem to point to a very different problem that is caused by the legacy of X 
itself.
The implied usage of DDC by leaving out frequencies is not really a smart 
move, and certainly not one a designer would make right now it he were to 
redesign this parser.  The new designer would correctly say that implying a 
configuration setting by leaving away some other settings is not just 
unintuitive; it basically makes for a lot harder debugging by configuration 
writers.

A much better solution would be to have an extra option (which defaults to 
yes when omitted) like 'option autoprobeFrequencies'.
Setting it to yes means any frequencies placed in the config file are not 
used unless the DDC fails.
Much cleaner since nothing is implied and no user-entered values are ever 
lost due to them being commented out.

This immidiately also means a similar option can be provided in the UI this 
thread seems to be spawned from making everything very clear.

Cheers!
