There is an opportunity here for Philips to step in if they have found out
anything about this.

Not absolutely, but likely. If the problem is the power supply rising too
fast than simply switching it on to the micro after it has stabilized
(essentially what I did) will give a fast and rather dirty edge. If it's
too slow than adding extra capacitance (what Tsvetan did) will slow it down
and presumably make the problem worse. Mine was a quick and dirty test but
it ruled out a simple sequencing explanation.
