OK, I am definitely missing something, because https://github.com/dumbbell/freebsd/blob/master/sys/dev/drm2/drm_pciids.h shows that line 491 is blank, which is the same thing I'm seeing on my checked out version. > You could post your dmesg to show what's happening when you load > the module. Nothing happens. kldstat shows that the radeon module gets loaded, but nothing shows up in dmesg. > Note that if the module loads ok, syscons goes blank because there > is no support in it for KMS yet.

Is there something that has to be done with the code in sys/dev/drm2/ before it can be used? Adam
