Guess Lee is right.
Does noise vanish when laptop is running on battery?
Erm, and what exactly is that laptop called?,
so I can avoid to buy one of those ;-)

But the
most intriguing part of the whole story: Not only did the noise
get louder at a lower latency, it also seemed to precisely double its
frequency when running at halve the number of frames. I even tried to
measure the frequency of the noise. As far as I remember, when running
jack for instance at 44100Hz, periodsize 32, the noise was at exactly
44100/32 = 1378Hz!
That is absolutely fascinating. I WILL investigate this; if it
coincides, we have a VERY strong case that this is the same problem.
