Even HorizSync 60 should do it - what /exactly/ you have in there isn't 
that important as long it's something that gives you 1024x768 at 60Hz.

Odd, that /should/ work - certainly does on mine ( iBook G4 but the 
panel should be the same as on yours )
Is that XFree86 or xorg? I had trouble with xorg 7.0 which produced a 
lot of flickering and random horizontal lines while NetBSD's xfree86 
did the right thing.
Where did you put Option "iBookHacks" "true"? It needs to be in the 
Device section or it won't have any effect. I also never tried to run 
it in 16bit ( which XFree86 will default to if there's no DefaultDepth 
statement in the Screen section )

have fun
