New AMD drm code

[Adam K Kirchhoff]

I'm wondering if there is some secret to getting the new radeon drm code up and running.  I realize it's currently very experimental, but I have a number of machines and cards I can test with. 

I've tried using both a standard -CURRENT kernel and one built from here: 

https://github.com/dumbbell/freebsd

However, in both cases, the radeon kernel module does not attach to my HD6950 when I load it.  In fact, a quick look at ways/dev/drm2/drm_pciids.h doesn't seem to show any newer Radeon HD gpus.

I have the feeling I'm missing something obvious..

Thanks.
