I found out myself already. It turns out that the gd package contains only 
the libgif files. The libpng files are in a separate package in Suse. After 
installing this package, and reconfiguring and rebuilding mrtg it produces 
.png files.
I was confused, because I asumed that gd no longer supported .gif. 
Apparently, it still does.
