I see. You could try out the WIP 5.6 Linux DRM branch to see if that fares
better:

https://www.unitedbsd.com/d/563-56-gpu-drivers-update

Or, see if this works. In the GENERIC config:

# genfb*          at pci? dev ? function ?
genfb0          at pci1 dev 0 function 0
genfb1          at pci0 dev 1 function 0

On the assumption that your _other_ Radeon card is connected to the VGA
port, we make genfb0 attach to it (and which will take over all displays
--no multi-card support on NetBSD at present, I'm told).
