this is mostly from freebsd (though it also exists in other versions
of the drm code) svn commits:

SVN rev 196470 on 2009-08-23 14:55:57Z by rnoland
Add kernel support for Radeon R6/7xx 3D.
You will still need Mesa from git and possibly an updated DDX driver,
but this is working fairly well now.

radeon_family is an enum, so ordering can be important.
sync up with what amd is shipping.

R600 doesn't support IRQs yet, so don't try to use them.

special thanks to robert noland @ freebsd for making this an
easy port!
- use err where appropriate.
- add machclass which should be x86 when i386 and amd64 and can be specified
in man.conf as:
_i386 x86
_amd64 x86
so that we can support merged pages. Nothing uses this yet.

I will send-pr for the next one... Looks like someone did not use DIAGNOSTIC
when made the changes.
