I've tested with the following combinations:
- append="video=atyfb:comp_sync:1,1024x768@70"
  Works perfectly: csync is high and good display.
- append="video=atyfb:comp_sync:1,hor_sync:1,vert_sync:0,1024x768@70"
  csync is high, but for some reason not hsync; display is good.
- append="video=atyfb:1024x768@70,comp_sync:1"
  Same results as first test.

The sync settings were checked with 'fbset -i'.

Hmmm. Wonder why you say that (considering the result of my last test).

Should these new options also be documented in Documentation/fb/?

Cheers,
Frans
