Frederik sent it to me, that's how I got the idea. SO credits for this go
really to you :-)

I would be very much interested in an improved project to orp that enabled us
to simply cut the resulting svg in equal stripes (and tiles). The same change
would be needed for xslt osmarender though, to keep them on par. Is there an
isolated diff that does this for orp? This change would be useful on its own
already.

Well, I certainly don't want to modify orp.pl to directly produce png files,
but if orp did the projection so that inkscape simply needs to render 1 svg to
a png for each zoomlevel and tilesGen.pl could take that png and chop it up.
That would be great.
