NetBSD already has DRM/KMS support. It's implementing all the same calls as linux.  
Making linux programs running under COMPAT_LINUX aware of this requires some glue.  
<!-- XXX, does it? -->

Similarly, running 32-bit programs on a 64-bit host requires some glue code.  
The 32bit glue code is already written for Linux, so can be a source of inspiration.


Milestones:

* Create a setup so that a linux glxgears/glxinfo can be tested (software acceleration should already work)
* Create glue so linux DRM ioctls are understood as NetBSD DRM ioctls, with no modification.
* Test a bigger program
* Create a setup for 32bit glxgears/glxinfo.
* Adapt linux 32bit compat code, being inspired by existing 32bit compat.
* Try to run a bigger program, like 32-bit NetBSD Firefox.
