My /var/log/XFree86.0.log has this line
(II) RADEON(0): Ranges: V min: 50  V max: 160 Hz, H min: 30  H max: 95 kHz, PixClock max 210 MHz
which seems to be related to this nearby prior line
(II) RADEON(0): I2C bus "DDC" initialized.

Note that the lines have "(II)", not "(**)".

I suppose that if your monitor supports the I2C/DDC protocol (AKA PnP?),
then X can get the "Ranges" as above and use it.  I had hand-entered the
same numbers from the Monitor's spec sheet, so I don't know if it
actually works automatically.
