Thanks, that did the trick. Here's a reference for others if needed:
Xorg.conf:
Section "Device"
Identifier "Radeon"
Driver "radeon"
BusId "PCI:1:0:0"
Screen 1
Option "AccelMethod" "glamor" # Doesn't seem to be used
EndSection
Section "Device"
Identifier "Intel"
Driver "intel"
BusId "PCI:0:2:0"
Screen 0
Option "AccelMethod" "sna" # Unsure if this works
EndSection
# lsmod|grep radeon
radeon 694017 2

Now I wonder if it's possible to start display manager and X with
DRI_PRIME=1? Or that doesn't make sense?
