thanks for these hints. I have got a working setup now. I did this
steps:
1. specified MonitorLayout ->
     (II) RADEON(0): Secondary:
      Monitor   -- CRT
   but now DDC
2. specified CRT2HSync, CRT2VRefresh -> still 60Hz
3. specified MetaModes -> I get 85 Hz at external screen

In MergedFB with "Clone" I get overlay only at internal-screen. With
"LeftOf" I get overlay at the external-screen. The option
OverlayOnCRTC2 doesn't help at Clone mode. The effect is:
(WW) RADEON(0): Option "OverlayOnCRTC2" is not used

And prior:
(II) RADEON(0): Validating CRTC2 modes for MergedFB ------------
(II) RADEON(0): CRT2 Monitor: Using hsync range of 60.00-100.00 kHz
(II) RADEON(0): CRT2 Monitor: Using vrefresh range of 50.00-120.00 Hz
(II) RADEON(0): Clock range:  12.00 to 350.00 MHz

(II) RADEON(0): Not using default mode "1024x768" (hsync out of range)
(II) RADEON(0): Not using default mode "512x384" (hsync out of range)
(II) RADEON(0): Not using default mode "1024x768" (hsync out of range)

n)
(II) RADEON(0): Not using default mode "1024x768" (hsync out of range)
[..]
(II) RADEON(0): Total of 18 CRTC2 modes found for MergedFB-----------

Any ideas?
