System: NetBSD rbixler 7.0_RC2 NetBSD 7.0_RC2 (GENERIC) #0: Fri Jul 24 21:05:10 CDT 2015 rcb@rbixler:/usr/obj/sys/arch/amd64/compile/GENERIC amd64
Architecture: x86_64
Machine: amd64
>Description:
I started using the NetBSD 7 branch on this machine in mid-May and,
initially, all looked good.  I upgraded about a week later and noticed
after the upgrade that the resolution was detected by default as
1024x768, when it should be 1920x1080.  I noticed one of the kernel
updates involved an i915 drikms update, which might account for it.
I'll give a complete "dmesg" output below with a default boot, when
the resolution is set to 1024x768.  Operative line seems to be one which
contains following text:

drm: GMBUS [i915 gmbus dpb] timed out, falling back to bit banging on pin 5

specify a VESA mode greater than 1024x768.  The correct resolution is
detected and all seems to work fine, despite that the following message
