Ok, forgot about that.

So, one of my mistakes was, I had set 
\setupexternalfigures[maxwidth=\paperwidth], that overrides all other float 
definitions.

With this (perhaps not minimal) example I get nearly what I want, but the image 
starts with the paper and is centered (x/y -1,5mm/0mm) where I want it to start 
on -3mm/-3mm on a left page, 0mm/-3mm on a right page. I thought my definitions 
should do that...
