That's fine if it works... but sometimes it just isn't possible to use
particular modes if you chose to do this, particularly if the system
configuration tool is conservative with its modeline generation or you
have an unusual set of hardware.

Usually, though, what you suggest is the best method, if for no other
reason than it avoids changing configuration files in such a way that
distribution-specific tools become confused.

They're useful for situations when you need a particular mode that is
not otherwise available for whatever reason, e.g. the mode is just on
the edge of what the monitor can do, or the aspect ratio is unusual.

If you're happy with the resolutions already available on your
configuration, there's certainly no need to use modelines.

With a modern X server, and a monitor that supports DDC, you can get
away with removing all of the monitor and mode specific stuff from the X
configuration file.  If your monitor doesn't support DDC, the only
details that you need to supply are the horizontal and vertical refresh
rate limits for your monitor.  I notice that a SLES 9 box here with X
installed has gone to the trouble of generating all of the modelines
appropriate to my monitor and graphics card.  On another machine where I
configured X by hand, I've got no monitor-specific details at all, no
modelines, and all works very nicely.
