a first version of the test files can be found here (7z, LZMA2 compression)
https://www.wuala.com/indiego/public/?key=caiCGLasLFmJ
i have tested four versions so far.
1. cmyk (default) page group
2. rgb page group
3. cmyk page group + pdf/x
4. rgb page group + pdf/x
no general problems so far (only spot color related)
