Are you using vesa_drv or intel_fb_drv? If you're using intel_fb_drv, that's your problem. If not, I can try running a basic Genode system on my AMD CPU & GPU desktop, and tell you whether it works for me.

Any laptop or PC I compile Genode on that has an Intel CPU works fine for the framebuffer.  Any PC or laptop I compile Genode on that has an AMD CPU the framebuffer doesn't work.  So far from what we have been able to determine is there is not support for AMD's framebuffering and any sort of interaction using an AMD CPU has to be done with a serial port, not standard video output.  If I am wrong in this conclusion, please correct me, but this is something we have actively found to be the case.

The update of seL4 is scheduled for version 17.08. Please see our road
map [1] for our planning.

Admittedly, I do not fully grasp the question. Are you referring to a
particular AMD CPU with integrated graphics? As far as I know, graphics
devices are usually realized as PCI devices and most cards support VESA.
Have you tried our VESA driver with your device?

We do not have a current ambition to focus specifically on AMD hardware
in the immediate future. If there is commercial interest, of course we'd
work on it as a commissioned project, but not on our own account.

Cheers
Norman
