I have tried the Aug 4th snapshot on a early-2015 13" MBP which reports:
addr, size	0xb0000000, 0x1437000
dimensions	2880 x 1800
stride		2944
masks		0x00ff0000, 0x0000ff00, 0x000000ff, 0xff000000

I'm a bit puzzled by the dimensions, as wikipedia says that the resolution
is 2560x1600...

The mid-2012 reports the same as in the original report...  But appears to
boot as the USB still gets accessed and I can push the power button, and it
will turn off...

My mid-2015 15" MBP reports:
addr, size	0x80180000, 0x13c6800
dimensions	2880 x 1800
stride		2880
masks		0x00ff0000, 0x0000ff00, 0x000000ff, 0xff000000

This appears not to boot as the USB drive turns off and stays off, and a
short press of the power button does not do anything...

Ok, on my mid-2015 15" MBP, if I set kern.vty=sc at boot loader prompt, then
the machine boots (I can shut it down w/ the power key), but the console does
not work..  So, it looks like vt is doing some thing on the mid-2015 15" MBP
that causes the machine to crash early on...
