XServer 1.18 on Lenovo T520/SandyBridge: need to load i915kms manually

Thanks for the update, it's working fine on my X230t/IvyBridge using
the modesetting driver!

I had some troubles on my T520: only the vesa driver worked, so I'm was
at a wrong resolution and without my external monitor :( :( :(

After some testing I discovered that everything starts to work
if I load i915kms before starting X. So it works for me now, too.

I'm writing up my configuration so it can be fixed and/or someone else
with this problem can find the workaround.

I'm running a fresh 11-STABLE:

crest2% uname -a
FreeBSD crest2 11.0-STABLE FreeBSD 11.0-STABLE #2 r314150M: Thu Feb 23
20:19:45 CET 2017     mathiasp at crest2:/usr/obj/usr/src/sys/GENERIC  amd
64

pciconf output for the card:

vgapci0 at pci0:0:2:0:	class=0x030000 card=0x21cf17aa
chip=0x01168086 rev=0x09 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '2nd Generation Core Processor Family Integrated
Graphics Controller'
    class      = display
    subclass   = VGA

X doesn't load the card when i915kms is not loaded before:

info: [drm] Initialized drm 1.1.0 20060810
(thats it)

If I load i915kms manually everything is fine:

info: [drm] Initialized drm 1.1.0 20060810
drmn0: <Intel SandyBridge (M)> on vgapci0
info: [drm] Memory usable by graphics device = 2048M
info: [drm] MTRR allocation failed.  Graphics performance may suffer.
intel_iicbb0 on drmn0
--- snip ----

If someone wants to fix this and needs more information or testing just
ask.

Thanks for your hard work!

Mathias

P.S.:

This is the xorg.0.log up to the driver selection if i915kms is not
loaded:
