Are you sure about this? I can't run X.org 7.0 at the moment, but I
checked the manpage and this syntax is not mentioned there; and
looking at the actual sourcecode of X.org 7.0 (function
RADEONGenerateModeListFromMetaModes in radeon_mergedfb.c), I don't see
how it can work - the parsing code always treats a dash as a separator
between the two monitors, so it would choke on an appended "-60". I
tried on X.org 6.8, and it indeed chokes as expected.
