amd64 DRMKMS Intel regression

[Piotr Meyer <aniou%smutek.pl@localhost>]

After success reported in [1] I have had some troubles with disks and
returned yesterday to tests. Unfortunately, fresh installation of 
NetBSD 7_BETA (dist kernel DRMKMS.201501091650Z) gave me only black
screen after 'startx' command. I was able to return to console and
terminate session by ctrl+c (X dumps core after that).
I tried -current kernel and workaround from [3] but without success.

Some data (dmesg before 'startx', dmesg after and Xorg log) are located
at [2],
