btw, in the end I wrote a small sdl_echo program to write argument to screen using SDL, included here:
http://dl.openhandhelds.org/cgi-bin/caanoo.cgi?0,0,0,0,112,775
it is used to report the absence of python (otherwise there would be no feedback)
it is very simple ofcourse...it may be worthwhile to write a program in the same spirit for simple yes/no dialogs.
ps to only thing I don't like is that the executable is 4k, but it needs a seperate ttf font file (often >100k)
