[Makoto Fujiwara <makoto%ki.nu@localhost>]

I've installed HEAD from nycdn to Panasonic Let's Note CF-SX2,
(20190105 version, and also checked with 201901111600Z).

In sysinst, screen gets blank, but extenal VGA works.
After installation, also LCD does not come out, but extenal VGA
works.

The part of dmesg is below and
