FreeBSD sonia 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r258334: Tue Nov 19 08:32:56 PST 2013     adrian@sonia:/data/1/adrian/freebsd/head/obj/data/1/adrian/freebsd/head/src/sys/SONIA  i386
>Description:
CPU:

CPU: Intel(R) Atom(TM) CPU N450   @ 1.66GHz (1666.51-MHz 686-class CPU)

Display:

vgapci0@pci0:0:2:0:     class=0x030000 card=0x83ac1043 chip=0xa0118086 rev=0x00 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller'
    class      = display
    subclass   = VGA
vgapci1@pci0:0:2:1:     class=0x038000 card=0x83ac1043 chip=0xa0128086 rev=0x00 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller'
    class      = display

Starting xorg simply hangs.

>How-To-Repeat:

>Fix:
Bill Paul fixed this for the exopc; the same bug and fix is here:

http://people.freebsd.org/~wpaul/exopc/

However, it's not clear why it works. It may be something else besides the xorg driver as I have no issues with Linux + intel drivers on a 2011 era Ubuntu (but a 2011 era FreeBSD suffered the same fate; I ran with VESA since then.)
