bingo that was it.  i missed that change, thanks for pointing that out 
Mark.  I'm able to load the i915kms module now.

next step is figuring out why the nvidia-drm module is causing a panic 
(this is one of those funky intel + nvidia GPU laptops).  but i get a 
core on that, and having the intel gpu load allows me to run X at least.

thanks everyone!
