OK, that's odd.  does the radeon driver not work here?  from
sys/external/bsd/drm2/dist/include/drm/drm_pciids.h:

  4:#define radeon_PCI_IDS \
  5:      {0x1002, 0x1304, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_KAVERI|RADEON_IS_MOBILITY|RADEON_NEW_MEMMAP|RADEON_IS_IGP}, \
...
281:    {0x1002, 0x67B1, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_HAWAII|RADEON_NEW_MEMMAP}, \

which should make it attach as a radeon?  libdrm and Mesa
also seem to want to radeon-ify it?

external/mit/libdrm/dist/radeon/r600_pci_ids.h:483:CHIPSET(0x67B1, HAWAII_67B1, HAWAII)

external/mit/MesaLib/dist/include/pci_ids/radeonsi_pci_ids.h:155:CHIPSET(0x67B1, HAWAII)

(radeonsi i think works with both radeon and amdgpu drm.)

i wonder what is happening here.
