Bonsoir !

Ok=C3=A9e, I did some tests...

None of the GENERIC/syscons kernels that I tested work with radeonkms.
It always fails at init of the ring command processor.  Tested:
	r265233, r265470, r266092, r266931 -- all fail

But using the VT config and the same sources, I found:
	r265233 and r265289 -- these work
	r265470 -- this fails

Most of the changes between r265289 and r265470 do not appear to be
relevant.  However, there are some changes to vm_fault.c and vm_page.c
that might have some impact.

I am out of time for today, now.
