There is a solution for this, but you probably don't want to know it: using
JOSM and the style Lane and Road attributes open the area around
http://www.openstreetmap.org/#map=17/47.94917/16.26273. (Note: a previous
change in JOSMs standard style just broke the rendering, so its best to
deactivate the standard to view it properly)
You will find a node tagged with traffic_sign=maxspeed;overtaking and the
appropriate rendering with two signposts on top of each other.

This is done via embedded svg-images, which are created on-the-fly
depending on the given tags. If you want to have a look at the specific
code, search for "node|z16-[traffic_sign]". The variable "traffic_sign_svg"
contains the svg image and "traffic_sign_top" the top of the next
to-be-added signpost (and after processing all tags it is equal to the
height of the overall image).

Best regards,
Martin

P.S: Anybody know how to disable the new default traffic sign rendering of
JOSM from within a style?
