It works fine on Debian Jessie for me, so I would assume that it should
be at least possible to do the same on FreeBSD with some tweaking.  The
only FreeBSD install I have on a PPC is serial console only so I haven't
really used graphics on it.

It looks like a Radeon 9600 RV350 from the pasted kernel log, which is
consistent with the Radeons that Apple shipped with the early G5 DPs.

Note to OP: if you can manage to get it to work, the framebuffer works
great, but Mesa still has some endianness issues.  There are a few of us
in the Linux and BSD world that are doing what we can to fix it, but
there's not a whole lot of us, so progress is slow going.  You'll have a
lot more luck with NV30/NV40/NV50 cards if you want OpenGL for now.

As I have a PowerBook G4 with a RV350, which obviously cannot be
replaced as it is a laptop, that should change soon hopefully.

Best,
