[PATCH 2/3] xfree86: If the driver found modes on an output, don't add more

[Adam Jackson]

Inferring modes from sync ranges is only valid if the monitor says it's
valid.  If the monitor says it's valid, then we'll have already added
those modes during EDID block parse.  If it doesn't, then we should
believe it.

If there's no EDID for an output, but sync ranges from the config, we'll
still add default modes as normal.
