--- Comment #16 from Johan Kuuse <kuuse at redantigua.com> ---
Just confirming what others already have mentioned here.

Using a fresh FreeBSD 10.0 RELEASE install:
uname -a
FreeBSD latitude 10.0-RELEASE FreeBSD 10.0-RELEASE #0 r260789: Fri Jan 17
01:46:25 UTC 2014     root at snap.freebsd.org:/usr/obj/usr/src/sys/GENERIC  i386


On a Dell Latitude E5400, with a Mobile Intel GM45 Express Chipset:
dmesg | grep 'apc\|agp'
vgapci0: <VGA-compatible display> port 0xefe8-0xefef mem
0xf6c00000-0xf6ffffff,0xe0000000-0xefffffff irq 16 at device 2.0 on pci0
agp0: <Intel GM45 SVGA controller> on vgapci0
agp0: aperture size is 256M, detected 32764k stolen memory
vgapci0: Boot video device
vgapci1: <VGA-compatible display> mem 0xf6b00000-0xf6bfffff at device 2.1 on
pci0

Xorg -retro works, so does starting startx, but running any
(cairo-dependent?)application causes an Xorg crash.
Workaround: Replace "intel" by "vesa" 
/etc/X11/xorg.conf:
    ###Driver      "intel"
    Driver      "vesa"

Not using WITH_NEW_XORG, as /etc/make.conf doesn't even exist.

With the Vesa driver, graphics quality is less than optimized, but I prefer not
to downgrading cairo and symlinking several others libs to fix what I hope is a
short time issue.

Opinion:
Not what you expect from a new RELEASE.
As mentioned by others, Intel chipsets are quite common out there, chances are
quite big this bug could have been nailed down.
I have been using FreeBSD since 3.0, and there have been few minor quirks in
releases in the past, but this is a big one.
