meta-crownbay: update README with new build instructions.

EMGD 1.6 added a new non-clickthrough Linux tarball download; this
changes the README to make use of it and also updates new directory
naming, etc.

+IIa Downloading and extracting the binaries using the EMGD Linux tarball
+------------------------------------------------------------------------
+
+The first step of the process is to download the EMGD 1.6 Gold Driver.
+Here is the current link to the URL which it can be downloaded from:
+
+http://edc.intel.com/Software/Downloads/EMGD/
+
+In the Download Now tab, select:
+
+Intel® architecture-based product: Linux Tar Ball
+Operating System: MeeGo 1.0 IVI Linux (kernel 2.6.33.3, X.server 1.8.0)
+
+That will give you a large tar file:
+
+Lin_EMGD_1_6_RC_1922.tar
+
+Extract the files in the tar file, which will in turn give you a
+directory named IEMGD_HEAD_Linux.
+
+The binaries are contained in an rpm file; you can extract the
+binaries from the rpm file using rpm2cpio and cpio:
+
+$ cd IEMGD_HEAD_Linux/MeeGo1.2
+$ rpm2cpio emgd-bin-1922-1.6.i586.rpm > emgd-bin-1922-1.6.i586.cpio
+$ mkdir extracted; cd extracted
+$ cpio -idv < ../poky-image-minimal-initramfs-emenlow.cpio
+
+Finally, you can copy the xorg-xserver binaries to the
+emgd-driver-bin-1.6 directory in the meta-crownbay layer:
+
+$ cp -a usr/lib meta-crownbay/recipes-graphics/xorg-xserver/emgd-driver-bin-1.6
+
+You also need to copy the IEMGD License.txt file to the same directory:
+
+$ cp IEMGD_HEAD_Linux/License/License.txt meta-crownbay/recipes/xorg-xserver/emgd-driver-bin-1.6
+
+At this point, you should be able to build meta-crownbay images as usual.
+
+
+IIb Extracting the binaries using the graphical ced application
+---------------------------------------------------------------
 
 These steps require that you run a graphical application in Windows.
 Windows 7 was used for these instructions, but it shouldn't matter
 which version of Windows you use.
