I just looked at your change to drm_getunique, and not only does that look
like a totally reasonable solution to the problem I was having, my
compositor starts up just fine with stock kernel, MesaLib from pkgsrc and
stock libdrm.

Forget my patches.  NetBSD-current is good.  And I can pull this down for
personal use if I want to run release code (which I will probably do for
my bare metal install and one of my dev VMs).

That said, I've still got stuff to work on here, as it does not cleanly
shut down (something that works fine on Linux and OpenBSD).  Instead,
the screen blanks and my fans spin up.  The machine hasn't hung or
panicked, as I can still do a clean shutdown via SSH.  I will dig more
on that front.
