The problem seems to be due to the panel powerup sequence. It looks like you need to do a well timed sequence of events when toggling the various LVDS related control bits for the panel to come reliably up. However, from trial & error, I've never been able to come up with a sequence that works perfectly for everybody. I suspect differnent panel models require different sequences. Unfortunately, ATI never answered my various questions about this. On the other hand, I seriously doubt that this can damage hardware. The fact is that if a flawky chip ends up dying while in linux, people tend to blame linux :-) If that happens in MacOS, they rightfully blame the hardware... go figure.
