interesting - so it seems like if i have drm-devel-kmod installed this 
will fail (missing or wrong linuxkpi_gplv2.ko).  this happens both if i 
install the pkg and rebuild the kernel, and if i build the kernel w/o 
the pkg installed.

yet, if i have the drm-current-kmod pkg installed, then "make 
buildkernel" it looks like the i915/amdgpu modules get build and an 
"installkernel" drops the linuxkpi_gplv2.ko module under /boot/kernel.  
at that point i am able to successfully load the amdgpu.ko.

finally, i install the drm-current-pkg fresh (without doing the above 
buildkernel/installkernel) i get the linuxkpi_gplv2 error as above.
