Allright, then I can live without going lower.

I can currently start pd using
-alsa -rt -audiobuf 2
and get click-free performance, as long as I don't the classic "Select
all.." and move things around in Tcl/Tk, which of course causes
drop-outs. Haven't measured latency with that setup yet, but it sure
sounds promising. Using the oss emulation of alsa works too, but
slightly more clicks when moving objects on the canvas.
