Where does this finding leads us? According to the specifications (http://www.amd.com/us/products/notebook/graphics/amd-radeon-6000m/amd-radeon...) this resolution over DP should work. Is it possible for the motherboard vendor to mess things up in some way?

That's the max theoretical mode supported by the chip. Whether or not you can drive a monitor that big probably depends on the type and speed of dram in your system since the GPU (display controllers, 3D engine, etc.) and the CPU have to share dram bandwidth.
