Have you tried loading it with kld_list in /etc/rc.conf?  Those get
loaded during boot, but it might be late enough to work.  That would be
automated, so it might be a little more convenient.

  I used the scfb driver in openbsd land for a work project . Currently I am
using 11-STABLE with the Radeon driver but at one point I had a different card
under 11.0 that didn?t work unless I used the scfb driver .

Thanks Carl.  Yes, that also worked.  

So, in summary, you can load the radeonkms.ko module from $kld_list in
/etc/rc.conf or put "kldload radeonkms" in /etc/rc.local.  I find it
to
be about the same convenience either way.
