Yeah, I ain't doing it either :)

See https://bugzilla.gnome.org/show_bug.cgi?id=571214 for a different
approach, which I think would serve us better.

It shouldn't be too hard to modify the existing combo boxes for
resolution and refresh rate to show a "Custom..." item.  Then, the
capplet would create a RANDR mode and switch to that when you hit Apply.

The GnomeRR wrapper API doesn't have a function to create new modes;
you'd need to patch that as well.

This sounds a lot more useful at first than going the way of "parse
Windows drivers for EDID blocks"...  If I had a monitor and it didn't
work out of the box, I'd google for the monitor's model, and a result
would come up with the correct resolution.  It's easier to type that in,
than to look at some (invariably unusable) manufacturer's website for
drivers.  If you are like me, you would have thrown out the CDs a long
time ago :)
