#1 [NetBSD] kernel patch for Let's Note CF-SX[234]

The model I've tested is Panasonic, CF-SX3, related lines from dmesg:
[     1.041396] i915drmkms0 at pci0 dev 2 function 0: Intel HD Graphics (GT2) (rev. 0x0b)
[     3.103214] i915drmkms0: interrupting at msi6 vec 0 (i915drmkms0)
[     3.152610] intelfb0 at i915drmkms0
This note PC has been needed some patch to use built-in LCD. I've been using a patch from sloss (toughbook version)

Then, I have three type of kernels tested:

  1. No change (-current)
    9.0 - 9.99.x
    -> Internal LCD was OK for a while after boot, but black out after drmkms activated
    -> external HDMI/VGA works. If external HDMI connected, internal also LCD works
      (and small font appears at console of both display, meaning not intelfb mode)
    
  2. 2. local (adhoc and almost debug print) patch (9.99.91 at the moment)
    -> Internal LCD and external HDMI both works
    
    xrandr output is:
